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 .
kf.solid.backends.fstab: Failed to acquire watch file descriptor Too many open files

$ tail -f some_big_file
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:
