Have some data stored in notebooks and is going to be a pain if I can’t get that back!! One of the top bars contains New note, New to-do, and New notebook. New to-do also has a box with a check-mark that never goes away. Just to see what it does I clicked on New to-do. The box for that area changed from white to blue and at that point Joplin hung.
At this point nothing works. Closing Joplin and restarting does not change anything - still hung. The screen looks exactly as it did when the problem started.
The latest Insider edition of Windows 10.
I’ve noticed something similar on macOS (10.13.6). The CPU usage spikes to 100% and stays there. Joplin (1.0.104) does not react anymore. This happens sometimes when clicking on New note. The only way to fix this is to kill Joplin.
I haven’t been able to determine on which occasion this hang happens - it seems sporadic and intermediate.
That resolved the disappearing data!!! Thanks.
Just ran a quick test and, looking via Task Manager, noticed that Joplin continues to run in the background when exited via the red X in the upper right corner. If exited by going to File and using “Quit” it goes away completely. Seems a bit strange; have always expected things to go away when closing via the “X”.
Well, it’s still a bug and needs to be addressed. In case of a hang, does your app also run with 100% CPU?
Next time I experience this I will create a spin dump. Maybe you could create something similar on Windows. In this case we can provide @laurent enough info to see where the hang occurs.
The CPU was very high, but can’t say whether it was 100%. Likely was . Both issues are easy to reproduce. I think the earlier part of this mail trail describes both. Don’t know how to get a Windows, in this case 10, dump.
Will be happy to do that, but need instructions. Was a mainframe guy and even after a long time, am still learning PCs.
Unfortunately I don’t know anything about Windows. The last time I had Windows installed on a personal PC was Windows 3.11.
On POSIX systems you’d create a coredump of the process to retrieve a stack trace. Or strace can be used as well.
On macOS there’s the Activity Monitor that allows you to select a process and do either a Sample process or Spindump. There are also the command line versions available for scripting or people who prefer the command line.
Something similar must exist on Windows. Maybe @foxmask or @zblesk can help out here. I believe both of them use Windows as their main platform.
Thanks. In the meantime, can you reproduce either problem on your system?
No I cannot. I mentioned before that these hangs occur randomly.
I have experienced some hangs, but they seem arbitrary and I can't seem to replicate them, so I won't be much help here. (And IIRC foxmask doesn't use Windows.)
I will create a spin dump the next time the hang occurs on my system. I just thought having a second one from a different OS might be helpful.
Here’s the spin dump (6.4 MB) of the last hang.
