             Summary: BDB JE cleaner can make no progress allowing for 
unbounded store growth
                 Key: QPID-7016
                 URL: https://issues.apache.org/jira/browse/QPID-7016
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall
            Priority: Critical


A user on a 0.32 derivative (including QPID-6734) encountered a problem where 
the store continued to grow (3GB per hour) even though messages were not 
accumulating within the Broker.

Analysis with the showed the the BDB JE cleaner was making no progress and in 
particular, JE's getEnvironmentStats() revealed that lnSizeCorrectionFactor had 
fallen to 0.079.  On restarting the Broker, the store size shrunk back to a 
normal size.  (Java Broker's Recovery evicted no messages).
