[Cinnamenu@json] Too many open files

[sphh]

 * Applet version/Build date: 4.13.11 (2021-04-21 08:32:25)
 * Cinnamon version: 4.8.6
 * Distribution: Linux Mint 20.1
 * Snippet or attachment of ~/.xsession-errors

Issue Sometimes when I open the menu, I get a lot of these entries in .xsession-error and then cinnamon restarts:

Cjs-Message: 20:48:53.199: JS LOG: [LookingGlass/warning] Cinnamenu file search:Error opening directory '/home/xxx/Software/github/cinnamon-spices-applets/azan@fahri.nurul.id': Too many open files

Steps to reproduce Difficult to say. Use the system for a long time.

Expected behaviour Cinnamon should not restart.

Thanks, I've found the problem. The temporary solution for the time being is to turn off the "Search home folder" option. This bug happens when you have a very large number of folders in your home folder. I need to change the search algorithm so that it uses less resources.

[sphh]

Ah, thanks for the solution. I switched it off, and now the menu reacts again swiftly. Before turning it off, when I pressed a key for the first time (to start the search), I got an immediate response, but after pressing the second key, there was a rather long delay before the menu got updated. Now I got the crisp behaviour back!! (And I also noticed that I never have used to search my home directory …)

[fredcw]

Is your home folder stored on a mechanical hard drive or an SSD? This may help me fix the delay problem,

[sphh]

It's on a SSD with a f2fs file system mounted with these options: rw,relatime,lazytime,background_gc=on,discard,no_heap,user_xattr,inline_xattr,acl,inline_data,inline_dentry,flush_merge,extent_cache,mode=adaptive,active_logs=6,alloc_mode=default,fsync_mode=posix
