Hi We have one topic publisher that publish 2M messages with 4 durable subscribers. Things go fine till we reached 1.7M we get the outofmemoryerror. AMQ is setup to use 5 * 20M log files, and derbydb jdbc persistence. It starts with -Xmx1024M and <usageManager id="memory-manager" limit="512 MB"/>
At the time of the out of memory, one of the log file is gone crazy and it's size is 415M, derbydb size is so big as well. We are using session client acknowledgment. and prefetch size of 1 (we need to serialize message consumption). each message is being acknowledged using javax.jms.Message.acknowledge(); did not find anything on how to change checkpoint interval for persistence. Any thoughts on what could be the issue? -- View this message in context: http://www.nabble.com/Out-of-memory-error-with-durable-subscribers-tf4487985s2354.html#a12798657 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
