Hi, My setup is:
- single AMQ 5.3 broker, with no persistence (persitent="false") - useDedicatedTaskRunner=false - two nio producers - around 70 tcp consumer - 5000 topics total with lastImageSubscriptionRecoveryPolicy and constantPendingMessageLimitStrategy=10 - producers do asyncSend - no producerFlowControl configuration - memoryUsage limit=4gb - tempUsage limit=2gb - -Xmx4gb with 64-bit JVM on Windows 2008 MemoryPercentUsage is constantly below 1, but all of a sudden I get a "Usage Manager memory limit reached for topic", and the producer hangs. Before messing with producerFlowControl I would like to understand what this means and what may be causing it. Is this a problem with the producers or the consumers? What should I monitor besides MemoryPercentUsage? I've read the following pages: http://activemq.apache.org/producer-flow-control.html http://activemq.apache.org/message-cursors.html Thanks, Danilo -- View this message in context: http://old.nabble.com/Usage-Manager-memory-limit-reached-for-topic.-Producer-hangs-tp26478478p26478478.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
