Open Tabs Without Crashing?

  • Until the latest snapshot - - I thought I had gotten past Vivaldi crashing because of too many open tabs. But with this release, it started again. I don't remember what corrected the problem last time and I have searched but didn't find the answer. And the crashing doesn't usually occur when I am using the program. But if I leave the web and check email or go to WordPerfect or Quicken, when I try to do back, V is down. I had been running V with between 20 and 25 or more open tabs with no problem. Right now, I have 12 to 14 open, then I drop back to Opera for the rest of my web searching, etc. Has anyone figured out the optimum number of open tabs that won't bring about crashing? My machine is a home built running Win 7 x64 on 16 gb of ram.

    I generally fluctuate between 10 and as many as 25, and have not had a crash due to too many tabs. Win 8.1 X64, running 32-bit Vivald on a 6-core processor with 10 Gb of RAM.

  • Running about 30 constantly right now, and often open up about 20 extra ones for a while until dropping back to my usual load. Have not crashed once.

  • Ayespy - Thanks. I re-installed the latest snapshot and right now I have 20 tabs open and working, so I will see.

    I searched for my previous question and problem and the solution - it was Vivaldi "timing out" and shutting down on its own. This required going into Performance Monitor and deleting all of the V processes and restarting. Whatever caused that on my machine disappeared on its own, so I hope that this is the case now.

  • It doesn't sound like exactly the same situation as yours, but v1.0.156.2 is the first version I've had (twice) the oft-reported "Vivaldi disappears but YouTube audio continues", requiring a manual closing of all vivaldi.exe processes to be able to restart. Apparently these were HTML5 videos on YouTube, as I have set vivaldi://chrome/settings/content > Plug-ins > Click to play which stops Flash Player from auto-playing on YouTube.

    The first time this happened, I also had opened Vivaldi Task Manager and left it running in the background, and although the 2 Vivaldi browser windows (7 tabs and 6 tabs) both vanished, VTM persisted and I was still able to see all 13 open tabs in VTM.

    The blue highlighted tab is the YouTube video whose audio continued to play after the 2 Vivaldi browser windows disappeared. (AFAICR, their wasn't a 14th tab that crashed and disappeared from VTM.) I was glad to have caught this, as I had suggested someone else who reported Vivaldi browser disappearing might try opening VTM and leaving it in the background to see if it remain visible and revealed anything useful when Vivaldi browser disappeared. In this case, VTM visibility persisted, but I don't notice anything useful in the info it displays other than it appears all tabs that were open are still "alive".

    Incidentally, the 4 lines outlined in green are 2 separate tabs appearing as only one process, the second of which (Why Linux is better) was opened by left-clicking on a link in the first. I don't think this has anything to do with Vivaldi disappearing, but is simply an oddity in how Vivaldi works that I hadn't consciously noticed before. (I had previously vaguely thought this was how a tab with forward/back history appeared.)

    Just noticing: For EVERY case in which the disappearing UI and remaining zombie processes has been mentioned, other than a known triggered crash, the commenter has either not specified what continued to run, OR, specified that a video continued to run in the background, playing audio with no UI. Again, nothing specified, or video specified. I think that may be important as the developers look to debug this.

  • I just lost V with 19 open tabs - when I went into Resource Monitor to kill the V processes there were none running. I clicked the V icon and it restarted right where it had left off.

    gdveggie - I just changed the Chrome plug-ins to Click to Play, even though Resource Monitor is no showing that You Tube was loaded when it shut down.

    I am back to 19 open tabs, but based on all of the responses and comments, I am beginning to wonder if one of the sites I am (was) on at the time caused the shutdown. I know that a number of the sites I log into start a video without any action on my part and I have to manually stop the video so that I can read the article.

  • I have also had times where the whole Vivaldi browser just crashes and all processes close. Hasn't happened enough for me to detect a clear pattern, but I think it has always been when I was probably near the max Vivaldi tabs for my system, and it might happen when I open a new tab, or am trying to highlight some text, or mouseover some active JS-driven menus, or …? But I don't think of that as being the same thing as when the browser vanishes while leaving all the processes running.

    As I understand it, the vivaldi://chrome/settings/content > Plug-ins > Click to play setting has no effect on YouTube's HTML5 videos as those don't rely on a plug-in whereas .flv videos do rely on Flash Player plug-in. I think more and more of the time YouTube serves HTML5 when possible, and I'd like to find a way to prevent them from auto-starting as well. I haven't looked for a means to do so, but if methods don't already exist via browser settings, extensions, or whatever, I'm sure they will be developed before long.

    Are there any particular reasons you like to use Resource Monitor rather than Windows Task Manager (as most do) or Sysinternals Process Explorer (as many do)? (I always use both Windows TM and PE, and now sometimes when I'm running Vivaldi, I'm trying to remember to also run VTM in background. I usually only fire up Resource Monitor if I'm trying to get an idea what is causing excessive HDD usage.)

  • I have Process Explorer on my desktop, but I have just gotten into the habit of using Resource Monitor instead. I don't Resource Manager's color quite as harsh on my monitor.

    As far as Task Manager, I avoid it because I have to click "Close Window" on the Windows Task Bar to shut the program. I am not sure if I am using Win 7's Task Manager or if I substituted something to replace it.

  • Looks like that when you kill Vivaldi because is stuck or has the UI already crashed (the fastest way to do it is taskkill /IM vivaldi.exe /F) it remembers the last state and tries to reopen all the killed process.

    So just delete the lasttab and lastsession files inside your profile before launching Vivaldi again.

  • @The_Solutor:

    Looks like that…

    Who are you replying to? (Looks like what?)

    …(the fastest way to do it is taskkill /IM vivaldi.exe /F)...

    I always have Process Explorer running so I just kill the vivaldi.exe process tree - probably about as fast as WinKey+R > taskkill /IM vivaldi.exe /F, but I don't have have one of my 26 (a-z) "remembered" Run window command (RunMRU) slots tied up with this one.

    So just delete the lasttab and lastsession files inside your profile before launching Vivaldi again.

    Not sure who (or what issue) this is directed at (?)

  • It's directed to anyone interested to the topic.

    Having 20 processes running instead of 5/6 is not surely the best way to keep Vivaldi stable.

  • I think I have discovered the site that caused me to close and restart Vivaldi because I was not able to navigate and I thought the whole program was locked.

    I was in TV Guide looking at program listings and I was unable to go up or down. I checked a couple of other tabs - I currently have 24 open tabs - and I could still maneuver around. I closed the TV Guide tab and restarted it back up. Things are working normally again.

    I am going to try this approach to see if it solves the hanging problem in the future.

  • Are you still having difficulty navigating on the TV Guide site? (or was it just at the point when you had the problem and went away after you closed the tab and restarted Vivaldi?)

    I have a lot less machine than you do (32-bit Win7 w 2GB RAM) , but I just visited the TV Guide site and checked and and didn't notice any problems on either page. But if you're still having problems on that site, post a specific URL so some of can check it on our systems.

    Getting back to your OP in this thread, with as much RAM as you have, I wouldn't think the number of tabs you're running should be a problem. Even on my system, I've had as many as 20-25 tabs open at least briefly (30-60 min) a couple of times. But depending on the page content, my machine can start to choke on 12-15 tabs, and I only find that I don't usually have to pay any attention to it at all when I limit it to 6-8 tabs (I'm starting to think some Dell Credant data protection software on my machine is part of what is choking on Vivaldi somehow, but that's a long story and I need to research it more). So I guess what I'm thinking is that it seems more likely your Vivaldi installation was having a problem with a particular site (maybe the TV Guide site), rather than "too many tabs".

    I have a couple more vague thoughts about the site, Vivaldi's cache, etc., but they might not be relevant at all, so I won't even try to formulate them unless your reply to the above makes them seem potentially relevant.

  • gdveggie - Thanks for the thoughts and suggestions, but I think I am okay for now.I am pretty sure that the TV Guide site has been the culprit. It isn't a lack of memory because I have been running 6 or 8 open applications, and Vivaldi has 21 open tabs and my memory usage is 13%.

    During some of the early snapshots, Vivaldi would cause a memory spike up to 50% and 100% of the cpu cycles. At that time I would either voluntarily restart the computer or the problem would cause a reboot on its own. But that has not been a problem for several weeks now (knock on wood).

    In fact I left the computer on this morning while I made a couple of trips and the memory usage had dropped several percentage points while I was gone, even with all of the tabs and applications open.

    So if that is the only problem I have tab-wise, I am in good shape. Especially because the TV Guide site is bookmarked and I can kill that site and reopen quickly.

  • Good, glad to hear it! 😉 If you continue to have problems on that site it might be interesting to see if the 32-bit Vivaldi handles it better (as the 64-bit is said to still be more "experimental" and buggy).


    or the problem would cause a reboot on its own.

    :ohmy: :S You mean a BSOD? That shouldn't happen at all, and is more typical of driver and/or hardware problems, but I suppose a buggy enough program maybe could trigger that (?)

    …Did you ever see any other reports of BSODs in the forums back then?

  • No, no BSOD. Just a reboot without any intervention by me. I have had machines lockup and I have had BSOD, but nothing like that. Weird. I went into the "Who Crashed" log and there was no record of the reboot. I guess it didn't qualify as a crash. Then I checked Event Viewer and it shows that these were unscheduled reboots. Really weird.

    After checking, I didn't think I was having crashes, so I haven't paid any attention to the threads on crashes. I am going to go back and if I find any similar reports I am going to tell the folks what I think causes them.

  • @litehorse3:

    That sounds VERY strange to me. Are you referring to Resplendence Software's "WhoCrashed"? If so, I believe that will only report system crash/reboots (often colloquially referred to as BSODs), and only if mini-dumps are enabled on your machine… ...but you won't get a literal blue screen unless your machine is set to stop the before the reboot and display the Blue Screen with basic crash info. There are also settings that control whether or not a mini-dump (or full dump) is saved; and if those aren't saved, there will be nothing for WhoCrashed to read.

    It's been too long since I last checked those settings on a machine for me to recall right now exactly what is involved, but if you haven't already checked, the Respendlence WhoCrashed site explains it all and how to change the settings.

    If that isn't what you mean, I'd like to try to follow up more on it if you have time, maybe via PM.

  • ~
    A few times, while testing the Bookmarks Panel, I encountered a strange screen where all controls disappeared, and all toolbars too.

    However, Vivaldi remained open.

    IIRC, I had clicked on the '+' button to CREATE a New Bookmark.

    The first time or two, I got frustrated and killed Vivaldi from the Windows task manager, and started over.

    But LAST time, I remembered a keyboard shortcut to close Vivaldi gracefully.


    Yes, ALT-F4 - our old friend from Windows 3.1, or maybe even DOS days.


  • Yeah, I still use Alt+F4 several times each week in Opera 12.16 that has a bug where windows like Bookmarks Manager, Downloads Manager, and "Print" pages from some websites open without the native Windows border with Minimize/Restore/Close buttons in the top right corner. If I want to keep the window open but be able to Minimize it, I can get the native border back with those controls by Maximizing the window from the Task Bar, then Restoring it, but if I just want to close it, Alt+F4 is faster.
