Hello

I am using jboss-eap-6.0 running under CentOS Release 6.3 Final) Kernel Linux 2.6.32-279.11.1.el6x.x86_64 GNOME 2.28.2

We are having two jms topics and two jms queues registered in standalone.xml file.  On moderate load on the server we are seeing the following error message in server.log

14-Mar-2013 14:44:39,466 ERROR org.hornetq.core.protocol.core.ServerSessionPacketHandler) Caught unexpected exception: java.lang.ArrayIndexOutOfBoundsException

Under normal scenario with not much load, we do not see this exception.  No idea why i am seeing this error in the server.log and i am new to JBoss/HornetQ

Also, in some instance we see the following warning message too.

27-Mar-2013 09:42:58,364 WARN  org.hornetq.core.server.impl.ServerSessionImpl) Replacing incomplete LargeMessage with ID=2412976

Any help on how to fix this issue or where to start debugging this issue would be  appreciated.

Thanks,

Cabir
