Hi,
I am trying to track down the reason for a massive accumulation of
ConcurrentHashMap in the heap of our long running Java process.
We are running Java 1.6 so I am pretty sure the known issue relating
to the 1.5 JVM doesn't apply here.
The URL below is a link to a screen shot of the heap analysis,
showing the accumulated memory. It seems to be root in a series or
region brokers?

I can also see that some JMX classes are in the root, could the
reason for the accumulation be related to having JMX enabled?
As far as we can tell, the queues are being serviced normally, and
this application generally runs for long periods of time without any
noticeable memory leak.
I'd be greatly appreciative of any ideas for strategies to get more
information about the source of the memory accumulation.
We're using Java 1.6 7 Active MQ 5.3
Thanks,
Matthew
Yuk - I thought I had purged all the use of ConcurrentHashMap - it
looks like you have a lot of active connections ??
