We are using Jboss messaging 1.0.1SP2 in our production environment. The following message keeps coming and the jboss queue gets backed up resulting in Jboss messaging not picking up the messages. We need to restart the servers very often to get away with this issue. Any ideas on this ? 2007-01-10 06:39:30,094 ERROR [STDERR] javax.jms.IllegalStateException: Should only be one entry in list.
