[jboss-user] [JBoss Cache: Core Edition] - jbosscache/jgroups memory leak

[hgardner]

Hello,

I am seeing a jgroups memory leak and am wondering if anyone can provide some guidance. Below is a partial jmap histogram dump showing the jgroups leak:  

468679912	990299	byte[]
227054264	5100368	char[]
124964040	5206835	java.lang.String

23326608	971942	java.util.concurrent.locks.ReentrantReadWriteLock$NonfairSync
23326608	971942	java.util.concurrent.locks.ReentrantReadWriteLock


We are using JBoss-Cache version JBossCache-1.4.1.SP6 and jgroups version 2.6.2. Any suggestions on how to work around this?

Any help would be greatly appreciated.
