you have set: Heap Space Memory to 1,2GB max
and your system memory is only 615MB? That is strange....

Maybe the system is caching to drive?

Hi Harjo,

Thanks for the reply . Actually that was the specification for the test server which is quite low . Please find the specification for the production server .

Processor: Intel(R) Xeon CPU E5645 @ 2.40GHz
Installed memory (RAM): 3.75 GB
System Type: 64-bit Operating System

Windows Server 2008 R2 Datacenter

System Information
Heap Space Memory: allocated=322748K, used=136663K, max=1267072K
Non-Heap Space Memory: allocated=95680K, used=95074K, max=180224K

We are also getting very high cpu utilization in the production server also . We are getting the CPU alarms for that.
Please provide your suggestions on this.


Thanks,
Ashutos.
