MessageConsumer and close() = hangs

[lexx]

Hello all,

We have several JMS-driven standalone 24x7 applications used with FUSE Message Broker 5.3.0.5.

All of applications works fine, except one - periodically it stops receiving new messages. This "stop" has very strange nature - no logs, no errors - nothing. After that "silent stop" we usually restarts this application and it always hang's on method consumer.close() - then we just kill the JVM-process.

This problematic application has one distinctive feature - it is the leader among all our JMS-driven applications on the number of produced/consumed JMS-messages.

Currenly this application "lives" 2-3 days, others - months.

Can anybody helps to find source of this strange behaviour?

All our JMS-applications use this JMS-specific options:

- Message listeners with AUTO_ACKNOWLEDGE (default onMessage)

- transport type - tcp

- wireFormat.maxInactivityDuration = 0

- soTimeout = 0

Problem was found - it was a deadlock in third-pary library (ehcache 1.5).

This thread can be removed.

Thanks.
