Hi.
I'm using a weblogic 10.3.5 as a test server (We deploy there the applications before going into production). The problem is that after a certain amount of deploys, the server becomes slower and slower until its mandatory to reestart because it crashes.
The error trace is this:

We tried with more memory and the same problem occurs. What kind of configuration/settings should we use/change in the server to avoid this problem?
Thanks.

"Caused By: java.lang.OutOfMemoryError: GC overhead limit exceeded"
The reason for this error is explained here: http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html#par_gc.oom
and here: http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html#cms.oom
You could try using -XX:-UseGCOverheadLimit, but that does not make the bad performance go away.
How many applications are you deploying?
