Environment

Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.1

Situation

Zenserver.exe increases memory usage.  zenserver.exe starts at about 250 MB and by the time it gets to about 650 MB, the ZCM server starts to slow way down (loading of ZCC is slow, users unable to login) and keeps grabbing memory until the server becomes totally unresponsive- usually at about 750-800 MB of memory.

Resolution

This is fixed in version 10.2 - see KB 7003225 "ZENworks 10 Configuration Management 10.2" which can be found at https://www.novell.com/support

Additional Information

The cause of the issue was found in the log4j.properties which caused thread deadlocks and high server utilization.
