Too many open files

[Ken Mankoff <mankoff@gmail.com>]

Hello,

I'd like to report a bug but don't know what package, and reportbug says I should email this list. I'm running Debian Trixie KDE Wayland, and repeatedly seeing "Too many open files".

Two examples:

$ dolphin . # dolphin window opens, but this is printed:
kf.solid.backends.fstab: Failed to acquire watch file descriptor Too many open files

$ tail -f some_big_file # file still tailed, but this is printed:
tail: inotify cannot be used, reverting to polling: Too many open files

Also, output of =journalctl -b -1= after a hard crash included the same message. I think it caused a system freeze once. Most of the time, thing still seem to work.

Maybe useful info:

$ ulimit -n # 32768

$ sudo lsof | awk '$5 == "REG" {print}' > list_REG
$ cut -d" " -f1 list_REG | sort | uniq -c | sort -n| tail 
    596 xdg-deskt
    808 xwaylandv
    853 Isolated
    871 emacs
    985 plasmashe
   1198 kwin_wayl
   1205 slack
   1877 chromium
   2336 ferdium
   3798 konsole

Any guidance to fixing this would be much appreciated.

Thanks,

   -k.
