 Hi,

I'm sorry for long delay, I had other emergencies...

However, I have found that all queues slow down, not only one. There are two
much more active queues and five which process significantly less messages.
When they slow down, there is abount 450k messages by first one, 250k by
second one and few 1000 by rest of the queues. 

OnMessages does not slow down, we have logged each mdb onMessage, and the
processing time does not change.

Out configuration is single instance, broker is LOCAL (but it was EMBEDDED
and there was the same problem), for message persistance we were using file
store, but now we are setting deliveryMode to non_peristent (we thought it
might help). We need sequential processing so, for each queue, there is only
one active MDB.

I have tried to pause/resume each queue, it helped for a few minutes.

Regards,

Adam
