Panic Message in Log - Slow perfomance

[Russ Todd]

I am getting extremely slow perfomance on the sim server and investigating foung the mxdomainmgr log filled with the following:

The server has been up for 2 days.

The mxdomainmgr process is consuming 2.4 GB and there are a number of Java processes that are consuming 1.5 GB of RAM.

The server has 16GB installed and nearly 14GB are consumed.

CPU Usage is around 30%


Recomendations on how to resolve would be great appreciated.

Hi,

Same Problem for me as well. I'm running HP SIM 6.3 on Windows 2008 R2 server with 28 G RAM. When i disable the PMP database the performance increase but after some days i still get the memory issue "Heap collection hitting upper limits".
I have change the heapsize in globalsettings.props but without any luck.
