Consumers are hanging and not receiving messages

[devnull <ji...@gmail.com>]

hi all, 
I have a producer and 4 consumer threads going to a single queue. The
producer and consumer are on different machines. After the consumer pulls
down 1950 or so messages it starts to hang. The primary consumer is in Java.
I have written a php test client using stomp that once the hang happens on
the java side I cannot even deqeue with the php stomp client. The queue
currently reports 3 million+ messages in it

here is my connection factory

here is a screen shot of my mbeans panel in jmx

I've tried restarting the server and java applications and both result in
the same outtime. After a couple thousand dequeues nothing else will be
dequeued from that queue. 

Anything else I can help post to debug?
thanks

Hi devnull,

did you make sure that your Java consumers do eventually ACK messages (i.e. is it ensured that onMessage() does always return)? You should also have a look at the subscription properties on that destination in jconsole.

Glück auf,
Dirk
