Rob Godfrey resolved QPID-6535.
-------------------------------
Resolution: Fixed
Fix Version/s: 6.0 [Java]
QPID-6249 will ensure that the number of threads is bound to a fixed size, and also handles the destruction of objects associated with a TCP connection more cleanly.

> Getting an OutOfMemoryError after running for several days. Attached is a thread dump showing hundreds of orphaned IoSender threads. At any given time there are fewer than 50 clients but many of them are not "well behaved". Here is the stack trace for the error but I don't really believe the LDAP calls are really the problem:
> 2015-05-08 03:01:19,000 ERROR [IoReceiver - /10.96.250.6:59923] (server.Main) - Uncaught exception, continuing.
