Activemq broker hangs

                 Key: AMQ-3710
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.4.2
         Environment: cent os linux version 5, 64 bit os, java 1.6 update 21
            Reporter: Krishnadasan T S
            Priority: Blocker

I am using activeMQ 5.4.2 as separate process in my production. more than 2000 topics and
600 clients are connecting to broker. Heap size (Old generation) area is taking nearly 1 gb
memory. Total memory allocated to jvm is 2.5 gb.

  Activemq is getting hanged 2 or 3 time in a day. by monitoring in JMX console What we noticed
is that at that instance of time nearly 100 new threads are created and all these threads
are NIO related threads. Once It happened at the time of GC(we gave a perform gc from jmx
for testing). It also happened at normal time also.

can you give any suggestion about what can be the issue.
