I have run into an issue with very high server load on a OES11sp2 server.
After a lot of troubleshooting we found that the cause was the adminusd process.

Last month i patched the server and we upgraded to novell-nss-4.16.4940-0.5.9, this contains the new adminusd component.
Specifically we found that it was related to volume space restrictions.

After turning volume space restrictions off the load of the server dropped from 10+ down to 0.66 (atm).
The strange thing was that adminusd wasn't showing up in top directly, but the us% was very high.

The problem only pops up when a lot of people are logged in and drops off again when the number is low.

Any idea to what is going on?
