Hi, 

I found a CME in the JBoss-messageing. 

Test scenario:

Vanilla JBossESB 4.7 with a simple flow. (file -> queue, bridge queue to another queue, queue -> file)

I kept this server running on a 2 core system with a load of 10 messages / sec. (ca 3kb messages).

I received many of these exception during the test. It caused some messages to stuck into the queue, but eventually they were redelivered. (Not after 5s, but after some other messages). They were counted in the 'DeliveringCount', and stayed like that.

Cheers,

Tamas
