Subject Exceptions with shared nothing master/slave
Date Tue, 19 Oct 2010 06:41:31 GMT
HI,

I've setup a master/slave configuration using the 'A Shared Nothing'
deployment.
I had two fresh ActiveMQ 5.4.1 deployment and two servers named activemqc
and activemqd.
I have edited the configuration following
http://activemq.apache.org/pure-master-slave.html.

But after some message get through the master the slave is giving me errors
I can't place. Has anyone on the list any ideas?
