I think i've found something...

2008-09-24 08:00:01.148 GMT Thread[ActiveMQ ShutdownHook,5,main] (XID =
125), (SESSIONID = 2), 
SELECT * FROM ACTIVEMQ_LOCK FOR UPDATE 
******* Table Scan ResultSet for ACTIVEMQ_LOCK at read committed isolation
level using exclusive row locking chosen by the optimizer

This is the only unusual query i've found.

Can this query block the checkpoint?
