Bug ID: 497424
Summary: fd leak with explicit sync (nvidia)
Classification: Plasma
Product: kwin
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: daron...@gmail.com
Target Milestone: ---
SUMMARY
I'm not sure where I should report this (nvidia, kwin, plasmashell or somewhere
else). Every notification, opening/closing plasmoids cause a lot of sync_file
leaks in plasmashell:
❯ lsof -p $(pidof plasmashell)
...
396r a_inode 0,16 0 1062 sync_file
397r a_inode 0,16 0 1062 sync_file
399r a_inode 0,16 0 1062 sync_file
400r a_inode 0,16 0 1062 sync_file
And plasmashell eventually crashes with:
plasmashell[2053]: error marshalling arguments for get_icon: dup failed: Too
many open files
plasmashell[2053]: Error marshalling request: Too many open files
plasmashell[2053]: The Wayland connection experienced a fatal error: Too many
open files
plasma-plasmashell.service: Main process exited, code=exited,
status=255/EXCEPTION
If I set __NV_DISABLE_EXPLICIT_SYNC=1 in /etc/environment this doesn't happen.
STEPS TO REPRODUCE
1. Open/close Kickoff multiple times
OBSERVED RESULT
sync_file leaks in lsof -p $(pidof plasmashell)
EXPECTED RESULT
No leaks
