Hi,

I have got this SLES10.3 / ZCM11.2 server ( upgraded from ZCM10.3.3 ) that I have been using for testing for the last few weeks before we migrate to 11.2 in production, hopefully. It only has about ten devices in the zone and one user source ( eDirectory ), so far I had no issues with it. Last night I left a couple of desktops to finish imaging ( which they did ) and added an iPrint printer policy and this morning the server was not responding - user login to the zone would not work ( hence no DLU ), I could not login to the control center or even bring up the logon page ( "waiting for host .." ).

I could ssh to the VM just fine, novell-zenworks-configure -c SystemStatus listed all services as running. After rebooting the VM everything seems to be back to normal. Here is zcc.log - any ideas about all those "java.lang.OutOfMemoryError: GC overhead limit exceeded" erros ? Sorry to post a long log like that.

Cheers,
Andrew
