Consumers from SLAVE

[Venkatesh Laguduva <lb...@gmail.com>]

We have two servers where we have two Master(M1, M2)/Slave(S1,S2) setups - M1
is bridged with S2 and M2 with S1; we have also grouped using the multicast
protocol; issue here is that in some cases for certain queue, I am setting
consumers from the slave to master. is this normal?

In a master/slave cluster, only one broker is active at a time; otherwise
you have a network of brokers, not master/slave.  Does that describe your
intended configuration?

If so, what you're seeing indicates that both brokers are active
simultaneously.  Try to confirm that by hitting both brokers' web consoles;
only the master should respond, so if both do then you have a problem.

The one thing I know of that can cause a slave broker to become active when
it shouldn't is an NFS failure that causes the master to lose the NFS lock
on the KahaDB lockfile; see
http://activemq.2283324.n4.nabble.com/ActiveMQ-master-slave-topology-issue-BUG-td4695677.html#a4695678
for a detailed description of what can cause that.  Does that scenario
match your setup?
