Package: gdm Version: 2.6.0.4-1 Severity: grave Justification: renders package unusable
GDM manages a few dozens of thin clients. After a variable time (few days), it stops working - clients start X server without getting any login screen. Gdm must be restarted (or even -KILLed) (shooting down any X sessions already running), then everything works again. This happened about 8 times in the last month. Problem is not specific to a single client, after THE MOMENT XDMCP works nowhere. Limits set in gdm.conf (MaxSessions=1024,DisplaysPerHost=4) can be never exceeded. I read about DNS-related problemswith XDMCP, but that does not seem to be the problem here; the DNS server is rather reliable. X server logs from thin clients show nothing interesting. Relevant portion of gdm debug log (obviously 12:52:40 problem happened, 14:35 killed and started again) is below. Help is very needed and greatly appreciated, I will be glad to send any additional information.
