I have installed Application Monitoring GUI in Webnms 5.0 + SP1 on unix machine.

The discovery seems to be working fine, all servers can be found.

But when clicking on Host Resources GUI, the GUI jsut hanging without opening anything. The log files I have received is as shown below:

[15 Feb 2011 06:13:11:165] APPLNERR: Exception in getting Host configuration details in HostResourceDataCollector at:
