    HornetQ creates paging files as soon as backup connects to primary

      I am seeing weird behavior.  When I create a 2 node replicated hornetQ cluster, with a very simple configuration, as soon as the backup server connects to the primary server, the primary server creates 0 length paging files (with their corresponding address.txt file).  They are 0 length, so they aren't really hurting anything (as far as I can tell), but this behavior seems wrong to me.

       

      Below is the relevant portion of the standalone.xml (not this is HornetQ 2.3.? in JBossEAP6.2)
