--- Comment #28 from Lewis Lakerink <le...@retsim.com> --- Ok, so setting the hard/soft fd limit to a high value appears to be an effective solution for me for now until this issue is resolved. Using Ash's xdotool script modified for pycharm, I got the kwin fd count up over 50,000 (took ~35 minutes) and no kwin crash, plasmashell is also still working fine before I stopped the xdotool script. I measured the fd's open by kwin using watch -n 1 "sudo ls -la /proc/`pidof kwin_wayland`/fd | wc -l" $ ulimit -Sn 1048576 $ ulimit -Hn 1048576 $ sudo ls -la /proc/`pidof kwin_wayland`/fd | wc -l 50074 For posterity sake, I changed my limits by editing /etc/security/limits.conf and adding the following lines to the end and rebooting. lewis soft nofile 1048576 lewis hard nofile 1048576 -- You are receiving this mail because: You are watching all bug changes.
