We are using Active 5.6.0.jar.We are seeing slowness due to Active MQ
threads.While analyzing the log i could find following message in
activemq.log
INFO TopicSubscription - TopicSubscription:
consumer=ID:SS-JHD-NMSMGT-1-38685-1364975764803-405:1:1:1, destinations=15,

is full, temp usage (106%) or memory usage (0%) limit reached, blocking
message add() pending the release of resources.
The *tmp_storage* size is some what around 110 MB.
Activemq.xml configuration is
<memoryUsage>
<memoryUsage limit="64 mb" />
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb" name="foo" />
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb" /> //How to set this parameter.Is this based on
JVM or based on the disk space
</tempUsage>
</systemUsage
When we took the thread dump we saw threads were hanging on Active mq
thread.
