I am running gdm 2.4.1.3-5.1. It is set to 5 minutes. After this event, I went to the remote location and unplugged the switch for a minute or so. The sessions restored without restarting. Also, I have a separate VoIP device at that location that logs disconnections and it shows none. It is dependant on the same network.
Also, there are several other workstations (including mine) on the same ltsp server (but wired locally) that did not have any problems. The three with the problem are remotely connected with a wireless link.
I'm thinking it has something to do with my network hardware. It has been known to pass certain traffic but not other. Voodoo.
Thanks for your help.

Christian,
While GDM is running, it's constantly pinging the clients, to make sure they are still alive. It's using the X protocol, not ICMP ping.
If it doesn't get a reply from the workstation in a specified amount of time (recent versions default to 15 seconds), then it assumes that the Xserver on the workstation has died, or the connection has been terminated, so it kills all processes associated with that session.
Also, if GDM dies for any reason, all of the processes for all of the sessions will also die.
Adding nfs-swap for the 32mbyte workstations is probably a generally good idea, I don't think it has anything to do with this problem.
You mentioned that it seemed like GDM was consuming some high amount of resources, so maybe there's a problem with GDM, and it croaked, thereby killing off all sessions. Then, because GDM is spawned from inittab, it was respawned, and that caused the login dialog to come back up on all of the workstations.

Yes, sorry. The session ended and presented the login right away. My log goes on to say a user logged in within a minute.

Christian,
When you say 'Crash', can you describe just what it does ?
Is it a kernel panic ? Or does X crash and restart ?
Were you able to get the stations running again ?

I recently had three workstations crash. They were all within seconds of each other. All three are at a remote location connected with ~10mbit wireless link.
They have all been virtually trouble-free for almost a year.
They each have 32MB RAM and I have since enabled 32MB swap.
Short, intentional network disruptions do not cause same activity.
I _think_ I remember seeing high utilization by a gdm-binary process around this time.
Anyone seen this sort of thing? Multiple workstations at same time?
Merry Christmas! c
