getting replication and memory errors in weblogic

[ankit jain]

1. What version of Ehcache you are currently using; 2.10.2
2. Paste the configuration for the Cache/CacheManager you have an issue with;-

   net.sf.ehcache.distribution.RMIAsynchronousCacheReplicator

3. Add any name and version of other library or framework you use Ehcache with (e.g. Hibernate);
4. Providing JDK and OS versions maybe useful as well.1.7 and Linux 5

We recently upgraded to weblogic 12 c and started seeing lot of issues with memory from ehcache replication

ehcache xml is as follows
