Timothy Bish closed AMQ-4136. ----------------------------- Resolution: Cannot Reproduce > Broker freezes on peak burst producer persistent message delivery > ----------------------------------------------------------------- > > Key: AMQ-4136 > URL: https://issues.apache.org/jira/browse/AMQ-4136 > Project: ActiveMQ > Issue Type: Bug > Components: Broker > Affects Versions: 5.6.0 > Environment: Java 1.6.0_35 > Mac OSX 10.7.5 > Reporter: David Israel > Priority: Critical > Attachments: activemq.xml > > > Expected: throttled messages when tempStorage reaches 100% > Actual: broker hangs and no longer delivers messages and cannot be cleanly > shutdown > Configuration: > - /conf/activemq.xml (attached) configuration: memoryUsage: 200MB, > storeUsage: 1GB, tempUsage: 400MB > - test configuration (/example/build.xml): max (# of messages): 65000, > messageSize: 10000 -> total message size: 65000 * 10000 bytes = 650 MB > Result: > - burst of 65000 messages to queue, initially loads into memory but quickly > gets dumped to tempStorage (12% memoryUsage) > - messages persisted in database > - producer throttling does NOT occur, potentially b/c memoryUsage is at 0% in > this peak/burst scenario when activmq stops responding > - activemq process hangs at 104% tempUsage, 0% memoryUsage, and can't be > shutdown without force kill > commands from standard release examples: > Start amq: > /bin$ ./activemq console > start producer: > ant producer -Ddurable=true -DsleepTime=0 > (Bug experienced with higher sleep times also.) > if you want to use consumers: > ant consumer -Durl=tcp://localhost:61616?jms.prefetchPolicy.queuePrefetch=1 > - watch memory and disk usage in jconsole > http://tmielke.blogspot.com/2011/02/observations-on-activemqs-temp-storage.html > workarounds: > 1) no tempUsage storage at all > \conf\activemq.xml -> <tempUsage limit="0 mb"/> > 2) try to hide tempUsage > \conf\activemq.xml -> <tempUsage limit="4 gb"/> -> 4 gb being much, much > larger than uninterrupted usage will fill -- This message is automatically generated by JIRA.
