WARNING: processCallbacks status 2

[Jim Goodspeed]

I am seeing the following Warning in my catalina.out log file - it is being
spit out every couple of seconds.  It's not causing a problem that I can
see, but I'm curious as to why it is happening.

WARNING: processCallbacks status 2

I am using Tomcat 5.5.9, Apache 2.2.10, Java 1.5.0_14 running on RHEL 4.  I
know that my version of Tomcat is old - we have plans to upgrade to the
latest soon (java as well), but for now I am stuck with 5.5.9.

We have two tomcat servers load balanced (config below)

ProxyRequests Off
    ProxyPreserveHost On

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass /maint !

    <Proxy balancer://app1>
        BalancerMember ajp://server1.domain.com:8009 route=app1-a
loadfactor=5
        BalancerMember ajp://server1.domain.com:8009 route=app1-b
loadfactor=5
    </Proxy>

    <Location / >
        ProxyPass balancer://app1/ stickysession=JSESSIONID
    </Location>


My AJP config from the server.xml file is below:

<Connector port="8009"
               enableLookups="false" redirectPort="8468" debug="0"
                maxThreads="200" minSpareThreads="10" maxSpareThreads="25"
                acceptCount="100" connectionTimeout="20000"
               protocol="AJP/1.3" />



As I said, I don't think this is causing a problem other than it is filling
up my log files, but I'd like to get to the bottom of it.




Thank you.
