    KeepAliveTimeout + httpd memory usage

    Yves Peter Newbie

      Hello everyone

       

      We have a problem with mod_cluster and memory usage/sticky session:

      If we set

      KeepAlive On

      KeepAliveTimeout 5

      MaxKeepAliveRequests 0

      globally in httpd.confmod_cluster looses the sticky session after a random amount of requests and routs a session to the wrong node.

      As suggested in the minimalexample we then set

      KeepAliveTimeout 60

      MaxKeepAliveRequests 0

      for the virtualhost that the JBoss servers connect to for their status messages. But now the httpd process uses more and more memory till it crashesthe server.

       

      Is it requered to set

      KeepAliveTimeout 60

      MaxKeepAliveRequests 0

      for mod_cluster to workcorrectly? I found no explanation in the documentation why it needs to be set like this.

      Is there an other configuration that could explain the memory usage?

       

      We use mod_cluster 1.1.0 on CentOS 5.4.

       

      Thanks for your help,

      Yves
