The TIME_WAIT state is a normal part of connection teardown when the connection is closed. If you are seeing lots of connections in TIMED_WAIT state then you can combat that by caching the connection on the client side (i.e. opening a connection for every message you send would result in lots of sockets in TIMED_WAIT. Also using springs DMLC without caching can produce the same affect). Perhaps your IBM MQ config is caching the connection and thats why you don't see it.
