      Hi,

       

      I see this message in my log :

       

      16:01:10,746 | WARN  | heckpoint Worker | PageFile                         | org.apache.kahadb.page.PageFile   458 | KahaDB PageFile flush: 3 queued w

      rites, latch wait took 172

       

       

      and production/consumption of persistent messages is very very slow.

       

      What is the origin of this problem and How can we solve it ?

       

      Env : ActiveMQ 5.3.0 running in SMX4

       

      Kind regards,
