Are there any messages on the queues in your broker? Lots of unconsumed/unacknowledged messages would certainly explain what you're seeing, and with PFC disabled there would be nothing to prevent the broker from blowing right through the memory limit (till it ran into an actual memory limit when it asked the JVM for some memory and was denied it).
If you're using a non-persistent data store (such as memory), then it's very expected that when you restart the broker and you lose all of the messages that had built up in memory, you'd go back to zero. No surprise there. On Mon, Sep 21, 2015 at 7:40 AM, lookers <colm.oloughn...@gmail.com> wrote: > Hi, > I am running AMQ 5.8 and the Memory percent used is greater than 100.
