Subject [users@httpd] Reason of dropping connections
Date Tue, 28 Jul 2009 08:59:27 GMT

I am facing one problem of dropping connections by apache load balancer.

System environment:

*         Tomcat (As backend servers ) - Apache 2.2.8 load  balancer (Using mod_proxy)

*         Apache server : Perform MPM setting

    StartServers          5

    MinSpareServers       5

    MaxSpareServers      10

    MaxClients          150

    MaxRequestsPerChild   0

*         Max thread at tomcat server 200

Getting error on tomcat server :

WARNING: Error sending end packet Broken pipe
        at Method)
        at org.apache.jk.common.ChannelSocket.send(
        at org.apache.jk.common.JkInputStream.endMessage(

Please any ideas ?
