Hi
Running SUSE 10.2 using CMS 2.1.1 with ActiveMQ 4.1 and stomp.
Set up is one producer and two consumers (for failover).
We have set JMSXGroupID in the producer, to make failover work, so only one
consumer consumes.
And on receiving messages the producer dumps the following errors:

I understand that properties are read only - is the CMS violating this?
