OE 11.3.2 - Admin Server throws JAVA Out of Memory Error

Hi all.

(I hope this is the appropriate forum)

We have migrated an OE application to a new server a week ago. Since then we had the following error three times, resulting in sever slow-down of the entire Application:

[STDERR] java.lang.OutOfMemoryError: GC overhead limit exceeded

We are not aware of any substantial configuration differences in the new implementation.

I have found the following references:

• http://knowledgebase.progress.com/articles/Article/8651?q=GC&l=en_US&fs=Search&pn=1
• http://knowledgebase.progress.com/articles/Article/P149523?q=GC&l=en_US&fs=Search&pn=1

Both of these refer to the same error, and suggest a start-up parameter to be used. IT seems to me that this is a work-around which treats the symptoms rather than the cause. I might not be understanding correctly. There is no indication that the root cause has been addressed in any later Progress Patch.

I did find the following article which recommends upgrading to OE 11.3.3, but the error is "heap space", not "GC overhead limit" - not exactly the same, so I don't believe it is necessarily relevant.

Since I suddenly have an unstable production environment - I would really appreciate any solid feedback or experience.
