Help! Random server crash (10.5.3) - services die.. couldn't spawn task??

[BlueC]

Every so often (maybe once a week) our 10.5.3 server has a fit. The symptoms are something like this:

Server Admin becomes unresponsive.
Server Admin reports that "This server does not have any services marked as configured"
The services "go down" - basically when we come in in the morning nothing works - no DHCP, no DNS, nothing.

The first entry in system.log that looks relevant is:

Jun 20 04:22:52 kiribati servermgrd[97]: pipe(status) error: 24
Jun 20 04:22:52 kiribati servermgrd[97]: Exception in doCommand: couldn't spawn task: path = /usr/sbin/sso_util, errno 24

Jun 20 04:23:25: --- last message repeated 1 time ---

This is followed later by many similar errors:

And these continue in a similar fashion ad-nauseum until we reboot the server. Full log file here: http://dpaste.com/hold/57713/

Anyone experienced anything similar or have any idea why this might be happening?

Thanks

Do you have any scheduled restarts? I had errors with the windows service not starting up and needing to be reconfigured after a reboot from cron. I set it to be a scheduled shutdown and start up through sys prefs and fixed it.

It may be a pain, but its better than a fresh install, you can reset and reconfigure open directory.
