It's been reported that during broker start some users get a message similar to:

15:26:29 INFO  Opening journal. Caught: javax.jms.JMSException: Failed to open transaction journal: Invalid argument

It could be this problem or the problem could be due to a bad os/jvm combination. See Known Bad OS and JVM Combinations
