Hello, We are using OpenJPA 1.2.0 in a WebSphere 6 web application. We are not using the EJB3 pack. We are seeing a very large proportion of the heap taken up by OpenJPA PCRegistry objects (as shown in image). We use compile time enhancement of our classes. Eventually with enough requests of under high load our servers fail with an OOM error as the heap is exhausted. The image below shows the heap analysis suspected leak subject. Also, this heap dump was taken when the heap was about 50% full.
We open, use, flush, close and set to null the EntityManager objects we create. Would anyone have any ideas as to the cause of this growth of objects that eventually leads to our OOM crash? Many thanks, Darren http://n2.nabble.com/file/n3166851/HeapAnalysis.jpg -- View this message in context: http://n2.nabble.com/Memory-Usage-tp3166851p3166851.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
