I am using activemq 5.9.1 configured as a jdbc masterslave setup using mysql.
We are having a problem where activemq suddenly stops noticing that there are pending messages in the ACTIVEMQ_MSGS table in the database. It continues to accept messages and put them in the proper queue. If you query the database, you can see the messages. mysql> select count(*), CONTAINER from ACTIVEMQ_MSGS group by CONTAINER; However, if you use the activemq web console to query the queues, you cannot see any pending messages. Restarting activemq fixes the problem. Attached is the stacktrace that I see right before it happens. Neil Gealy
