Was working fine for 2 weeks now, now I get a Service unavailable! 503 error.

I am running SLES 10 SP1, OES2 and ZCM 10.1.1, just updated ZCM to 10.1.1 from 10.1.

Everything else works, ZENworks Control Center, Remote Manager, iMonitor

On Netware I had to run PKIDIAG and SDIDIAG to fix a simular issue every few months. What are the Linus versions of those?
