WARNING: processCallbacks status 2

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.

Jan 5, 2009 3:27:09 PM org.apache.jk.common.ChannelSocket processConnection
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.

Thanks for the quick response - I'm glad it's nothing to worry about.

Yeah, this should probably be lowered to DEBUG level logging.  It usually 
happens when Apache drops the connection before Tomcat can send the "I'm 
ready for the next request" message.  As such, it is pretty harmless (other 
than disk space).  After this, Tomcat will just send the Thread back to it's 
pool to await another connection.
