Bug Description

I have installed AppFlowy via snap, flatpak, and finally deb/dpkg as after upgrading the snap the app crashes a lot. I was finally able to get a console output from the deb package and it gives me the following error:

...
(AppFlowy:138985): Gdk-CRITICAL **: 13:25:58.631: gdk_device_get_source: assertion 'GDK_IS_DEVICE (device)' failed

Aborted

This is in Ubuntu 25.04

How to Reproduce

Launch AppFlowy, do stuff, do more stuff, and eventually the app will crash. It does not seem related to user input. Often it is when switching context back to the app.

Expected Behavior

That the app would not crash.

Operating System

Ubuntu 25.04

AppFlowy Version(s)

0.9.9

Screenshots

No response

Additional Context

Similar crash pattern across snap, flatpak, and deb.

Hi @spmp, can you check the current system limit using ulimit -n?

You can try setting a larger limit and then relaunching the application.

Thanks for the suggestion, I set hard limits to max system wide for my user, but no dice sadly:

{"msg":"Skipping reconnect, already connected","time":"09-17 11:18:17","target":"sync_log"}

(AppFlowy:7220): GLib-GIO-ERROR **: 11:18:17.175: epoll_create1 () failed: Too many open files
Trace/breakpoint trap

and

ulimit -u
59887

The error in the original message of not being able to save is gone at least 😉

I have the same problem and it's very boring. I changed my system limit but it still crash at random moments.
I use Fedora 42 and I use AppFlowy 0.9.9 with Flatpak. Notice that I use a custom icon theme.

Here are the logs (some parts are in french) :

OK, so I went a bit over the top and had a look at lsof every 5 seconds, and this was mostly when the app was not in focus. The file count increases constantly and the app crashes when resuming focus when file count is greater than 1024.
I also kept a list of all the files each time.
The diff between them is largely IPV4 connections like:

Also worth noting that the crashes seem to log me out on my other device - my iOS app. Web app stays logged in, but that's got other issues ;)

I have been monitoring the number of open files whilst in an active session, the number of files stays stable around 1294 before AppFlowy eventually crashed on a ctrl+x - so yes, open files, but maybe not. I will see if the number gets higher.

Can you try this version: https://github.com/AppFlowy-IO/AppFlowy-Builder/releases/tag/0.10.0-250918-0747? We've added some logs to help address the issue.

OK, tried with 0.10.0, open files (including network connections to about 1294, open files to around 338, then crash.

@spmp can you check if you have the following folder on your machine? ~/.local/share/io.appflowy.appflowy/*/http_cache/tmp/*. It may be located in a different path based on your installation method, but it should end with http_cache/tmp

@spmp Can you check your data folder to see if any of them contain multiple files or folders? If so, please let me know the names of those folders.
