Severity of HQ214084: Invalid concurrent session usage.

How severe is the "HQ214084: Invalid concurrent session usage? ... warning.

Does this mean data corruption or a deadlock is likely to occur? Or does this mean that as hornetq this may become thread "unsafe".

I'm running into this warning occaisionally on the system I am working on currrently. All functional tests seem to pass even if I put the system under some stress, so I am just wondering how urgently I need to fix this.

JMS 0r HornetQ sessions are *not* thread safe and should only be used by a single thread.

I've seen some really bizarre behavior when sessions are used concurrently, data corruption being one such problem.  I'd say it's pretty severe.

Justins is correct, what can happen is that messages are acked out of order and since a message ack acks every message before it messages can disapear and data gets corrupted
