Hi,

I am using apache 2.2.9 with mod_proxy_ajp to tomcat 6.
(Upgraded from 2.2.8 as cping/cpong did not work)

I keep getting tomcat socket exceptions as if apache has closed the ajp connection before tomcat can respond.

My Balancer settings are such that the ajp connection is closed on every request the apache timeout is 30secs and the tomcat connector is 20secs. As follows:

ProxyPass / balancer://Cfu/ stickysession=JSESSIONID nofailover=Off timeout=30
#ProxyPassReverse balancer://Cfu/ /
ProxyErrorOverride On
<Proxy balancer://Cfu>
BalancerMember ajp://X.X.X.X:8009 route=herring ping=120 keepalive=Off flushpackets=on disableReuse=On
BalancerMember ajp://Y.Y.Y.Y:8009 route=haddock ping=120 keepalive=Off flushpackets=on disableReuse=On
ProxySet lbmethod=byrequests
</Proxy>



The following error keeps occuring in error_log

[error] (70007)The timeout specified has expired: ajp_ilink_receive()

This is the tomcat exception:

The tomcat ajp connector configuration is as follows:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
maxThreads="2000" bufferSize="256" connectionTimeout="60000" />



Any ideas on this one appreciated as it is nightmare...


Cheers
