Hi All, I am having "java.lang.OutOfMemoryError: Java heap space" error while starting an activemq broker. I am using: apache-activemq-5.9.0
The broker was configured for persistent storage using oracle database. The broker could start normally, then i manually created an queue and input some persistent messages into the queue on the localhost activemq console. As was expected, three tables, ACTIVEMQ_ACKS, ACTIVEMQ_LOCK, and ACTIVEMQ_MSGS, were created. The messages were stored in ACTIVEMQ_MSGS, and after stopped the broker, those messges were persistent in the table. Up to now, all the processes worked OK. However, after i restarted the broker, "java.lang.OutOfMemoryError: Java heap space" error occured. Another obervation, if the ACTIVEMQ_MSGS was dropped or all messages in ACTIVEMQ_MSGS were deleted, the broker can once again started normally. 2014-04-09 12:24:06,039 | ERROR | Failed to load: class
