Hi Per,
Is there a pattern to this, i mean does it stop every time after a
certain number of messages are consumed ?
What is the size of the messages ?
Could you turn off XA (SupportsXA=false, and no transaction in MDB
method) and try the same use case, this would help us narrow down the
issue.
Are there any errors/messages in the ActiveMQ log.
Thanks
