Subject AMQ 5.4.0 Memory Leak
Date Tue, 01 Feb 2011 19:27:43 GMT
Over a period of weeks we are seeing a gradual reduction in the JVM Heap


When I do a bstat I get numbers like: 

 TotalEnqueueCount = 5,070,691 

 TotalDequeueCount = 5,068,600 

 TotalMessageCount = 74 


Supposedly I should get TotalEnqueueCount = TotalDequeueCount +

but clearly there are over 2,000 missing messages! 


Rebooting does not clear up the problem. 

This is a production environment. 

How do I find and clear out these "missing" messages? 


Any suggestions on how to determine the cause?
