Subject JPA - PCRegistry consuming 80% of Java heap - Production Error - Help!
Date Fri, 10 Sep 2010 20:34:21 GMT
We have a J2EE App running in Weblogic 10.3 and are receiving
OutOfMemoryException's.   A dump of the heap shows that
org.apache.openjpa.enhance.PCRegistry is taking up 79.91% of the heap
(see below).

Class Name      | Shallow Heap       | Retained Heap       | Percentage
---------------------------------------------------------------------------------------------------
class org.apache.openjpa.enhance.PCRegistry |  16       |
234,453,760             |     79.91%
---------------------------------------------------------------------------------------------------

JVM Params are listed below

-Xms1024m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=256m
-Dweblogic.Domain=mydomain -Djava.awt.headless=true -Duser.language=en
-Duser.region=US -Dweblogic.Environment=prod

We are using OpenJPA shipped with WL10.3, the name of the JAR file is
org.apache.openjpa_2.2.0.0_1-1-0.jar.

The JPA Runtime appears to be using BEA Kodo 4.2.0load03

Has anyone ANY idea what is going on here. The server runs out of
memory after a week or 2, and needs to be recycled.

Any help greatly appreciated :-(
