Subject Re: Publisher stops publishing when a subscriber is attached to that topic
Date Fri, 08 Jul 2011 15:55:31 GMT
Is your subscriber slow by any chance and not keeping up with the rate
at which msgs get produced?
The topic subscription inside the broker then fills up with msgs until
you hit a configured memory limit. 
Once the limit is hit, producer flow control kicks in and stops the
producer until enough msgs got consumed
to continue.

I bet producer flow control is kicking in. After some time producer
should resume.
Also, try a slower producer rate to verify this.

Hope this helps.
