SIM 6.3 - Java out of memory errors

[shocko]

gettings these on SIM after running for a week

mxdomainmgr(error): Received remote RMI exception: Error occurred in server thread; nested exception is:
java.lang.OutOfMemoryError: Java heap space.

Anyone else getting them?

I would check first if your mxdomainmgr has a memory leak. 1 - 4 GB of virtual memory should be available. The log files will give you also a good indication if you have a special problem. How many managed systems do you have?

Only about 300 Prloiant Servers and 300 iLo cards. Not huge

In this case it could be a simple communication problem which is consuming the memory. You can check with netstat -an if you have an huge amount of blocked connections or increasing number of close_wait entries.
The port number will give you an indication which part of SIM has the problem. In most cases this indicates credential problems.

If you have 600 objects in side SIM with the default polling interval of 5 minutes this could be the reason.

But I would also check the SIM logs for other exceptions perhaps the heap space was to small during a normal RMI operation.

Do you see java stack dumpes in the diffrent log files ?

Do you have also IRSA installed on the SIM server?
