I have memory leak with jgroup replication and ehcache that makes an OutOfMemoryError. We tried different configuration for CahceManager but we're running out of idea. If someone already encounter the problem.
Packages versions :
- ehcache : 2.10.0
- ehcache-jgroupsreplication : 1.7
- jgroups : 3.6.6.Final
Leak identification :
One instance of "org.jgroups.protocols.pbcast.NAKACK" loaded by "org.ow2.jonas.web.tomcat6.loader.NoSystemAccessWebappClassLoader @ 0xc172f9e0" occupies 829 313 120 (88,02%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Segment[]" loaded by "<system class loader>".
