Hi,
Versions:
JBossCache - 3.1.0.GA
PojoCache - 3.0.0.GA
During my endurance tests I get such exceptions
1)

Does enybody know why?
How to reporoduce error:
To start a test you have to:
1) Copy pojo cache configuration on two nodes (I have cluster comprised from two nodes in LAN)
1a) My JVM config (on both nodes):
JAVA_OPTS="-Xms1200m -Xmx1200m -XX:NewSize=150m -XX:MaxNewSize=150m -XX:MaxPermSize=128m -XX:SurvivorRatio=15 -XX:+UseTLAB -XX:TLABSize=64k -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:MaxTenuringThreshold=32 -XX:CMSInitiatingOccupancyFraction=66"
1b)
2) Deploy web app on one of node
3) Go to web app web page
http://firstnode_ip:8080/pojocache-load-test/index
4) Choose section
Test with all remove operations running constantly.
and enter values:
500
Object live time in ms: 180000
and Run test.
Error should be shown after memory allocated on heap reachs its upper limit (from top totally allocated memory shows about 1.6GB)
