Subject Re: Possible memory leak in statistics gathering
Date Mon, 18 May 2009 22:07:54 GMT

I can check the 5.3 snapshot, but I don't see the relationship between the
two leaks.

In my scenario, the consumers and sessions aren't meant to be reclaimed;
they're meant to be long-lived. The problem is that they seem to be hanging
onto a couple of Statistics objects for each message they handle.
