Server getting hanged when invoking a flow service

[VishnuCharan]

Hi All,

When I am invoking a service from my webMethods Developer the server is getting hanged and we are getting the below logs:

2010-10-06 16:11:27 BST [ART.0114.1007E] Adapter Runtime: Error Logged. See Error log for details. Error: [ADA.640.5001] Unexpected exception executing adapter service: FetchAndInvokeEJB
PermGen space
2010-10-06 16:12:11 BST [ART.0114.1007E] Adapter Runtime: Error Logged. See Error log for details. Error: [ART.0000.0000] PermGen space
PermGen space

We tried to increase the heap space but still we faced the same problem.

Can anyone please help me to resolve this issue.

Many Thanks In Advance,
Vishnu Charan.T

It sounds JVM permgen server issue …

Check this resolution:
The PermGen space is used to hold the java classes which are used by IS.
We recommend to use a tool like VisualVM which analyses the processes being started in a JVM.
You may run it during the start of IS.
It will return the values that are defined for PermGen and MaxPermSize and show how much of both is needed by your IS. You then can increase it accordingly.

What does the service do? Is it a Java-Service? Does it contain a loop of any kind?

I would suspect there is an infinite loop involved.
