An Ubuntu Lucid server on which people log in using SSH, and $HOME is mounted through Kerberized NFS4. The thing is brought almost to its knees with "state manager failed" in /var/log/syslog, repeated hundreds of times a second.
Turns out logging out from SSH removes Kerberos Credentials, and if a process remains doing I/O to $HOME, then rpc.gssd will start spamming the syslog. There is a fix that reduces the spamming, but it is nog yet in Lucid(!).
So we tell the ssh daemon not to remove the credentials, by this setting in /etc/ssh/sshd_config:
GSSAPICleanupCredentials no

As a side note, the reason that I/O was still done to $HOME after logout may well be that Matlab was used without modifications to its default working directory. Mindful users will do I/O to local disks instead of network-mounted $HOME, and change the Matlab WD (untested, maybe also read this) from their Matlab programs before logging out. |
