They don't seem to share any Object.waits in common.

If you have java1.4.1 it will tell you about any deadlock.

You are looking for:
Thread1 waiting for A
Holds B

Thread2 waiting for B
Holds A

That doesn't look right???

Do you see a FioranoSession.run() ?

Adrian

[adrian.brock]

You'll have to ask Fiorano what it is doing?
It should only retrieving messages in the ConnectionConsumer
It shouldn't be waiting for messages here.

I contacted Fiorano who said there might be issues with 5.21 and suggested I retest with FioranoMQ 7.0

I have just done that and everything works perfectly.

That's good news for JBOSS 3.2.2RC3 and FioranoMQ 7.0 but very bad news for me as I can't essily migrate to FioranoMQ 7.0 (or even JBossMq) at present.

MDBs defintely do work for FioranoMQ7
