- I ruled out memory issues… I tuned up memory to 3G (should be plenty) and
enabled GC logging and there are no full GCs.
- I disabled producerFlowControl…
<policyEntry queue=">"
producerFlowControl="false"
advisoryForConsumed="true"
gcInactiveDestinations="true"
inactiveTimoutBeforeGC="60000”>
… still experiencing the same symptoms… A restart of ActiveMQ resolve the
issue for about 5 minutes… then my workers come to a crawl :-(…
