Re: Re: problem joram connector for jonas ??

Hi Sontung,

You might post  your message on the JORAM mailing list to get quick 
answer as it is related to the JMS stuff.
No matter, i put it in cc.

It seems that you've defined a max size in your queues (10) what could 
explain the behavior :
- under heavy load, the queue is  full (10 messages are pending)
- JORAM moves the extra messages in the DLQ (or DMQ)
- however there is no DMQ, thus the extra messages are deleted

@JORAM team: please, may you confirm this analysis ?

Regards;
