Subject Remote Durable Subscriber not receiving messages, but able to send
Date Thu, 27 May 2010 08:59:52 GMT


I've the below cluster set up for my application:

Machine 1: Publisher Process, Subscriber Process, ActiveMq broker service
Machine 2: Subscriber Process

Both the m/cs are in the same network.

My Subscriber processes ping the Publisher process only on startup;
otherwise they only receive messages. Machine 1 Subscriber is able to both
ping the publisher and receive the messages as both of them are on the same

The problem I'm facing is that, Machine 2 Subscriber is able to ping the
Publisher and the publisher is receiving the ping message; but its not able
to receive messages sent by the publisher.
The problem is not reproducible as its happening with only one particular
set of cluster m/cs. The same setup deployed on a different cluster works
perfectly fine.

I've ensured that firewall is not running on these m/cs, as one of the posts
in this forum stated a similar kind of problem and the hint given was
firewall blocking.

Any possible reason/solution for this problem is highly appreciated.
