Exeprienced high CPU on novell-xsrvd and troubleshooting revealed that my NTP source was down, as soon as I pointed to a stable ntp source novell-xsvrd behaved again.
The real issue is in during this troubleshooting I stopped the service and started it again, and stopping it the first time release 1GB of memory (server uptime 33 days) and starting it again only used a very small amount of extra memory.

Any known bug or experience on this ?
