Bug#966198: gdm3: Defunct gdm-session-worker processes occationally remains unhandled.

[Mad Horse]

Package: gdm3
Version: 3.36.2-1
Severity: normal

Dear Maintainer,

Sometimes defunct gdm-session-worker processes may appear after logging out
from a gnome session, which usually lasts several hours, but sometimes
logging
out from a gnome session lasting only one minute can trigger this
phenomenon.

These defunct gdm-session-worker processes are owned by the user
"Debian-gdm",
and their cpu time last only several seconds.

These defunct processes do not clearly impact the functionality of gdm3, but
they occupy available process slots, and cannot be manually cleared unless I
restart gdm3 with no gnome session active (via console or ssh).
