Subject Re: Messages stuck in pending
Date Tue, 08 May 2012 16:36:13 GMT
Hi Luke,

could you check the number of consumer on the queue ?

I saw a similar issue where my consumer was present while the load was 
not too high, and on heavy load, the consumer disappears and so the 
messages stayed in pending.
