Problem 1: they seem to just hang forever on logout. The user display just hangs there, and the cursor moves, but nothing will activate. letting it sit like that, it takes about 2-4 minutes to finally logout.
ctrl-alt-backspace restarts x, but that's not too elegant.
Problem 2: problems with either the .gconfd or .gconf home directories getting corrupted. in this case, the problem is on login. x starts but it is in the same condition as above--the cursor moves but nothing will activate. ctrl-alt-backspace works, but there are instances in the process table of gnome-panel and some kind of "bonobo activation server". killing them sometimes helps, but strangely it still shows up in the ptable and if I kill it again the system says "no such process".
rm -rf'ing the .gconfd and .gconf of the affected users fixes them up, but they have to redo their preferences, etc.
it seems likely to me that the gnome demons are trying to clean up on logout, and out of frustration we ctrl-alt-backspace, and this leaves the config files corrupted.
I'd say we have nfs problems except our apps move a lot of data through nfs and we are having no problems with corruption.
Any ideas are welcome. The machines are kept updated with "yum update" every week or two. We've had these issues from the beginning tho, just seeing them more now that we have more machines on the net.
When I watch the connection on ethereal it just seems to hang for a long time, no packets either way, then finally times out (or completes) and exits.
Sometimes the machines log out just fine, too...
Thanks, John
