mod_jk 1.2.8 socket_timeout property on solaris 2.8 - doesn't work

Java Developer-2
We have mod_jk 1.2.8 with apache 2.0.53 on solaris 2.8 connecting to JBoss
4.0.2 on solaris 2.8.

The number of apache child processes grows gradaully and upon reaching
around 150 the system response degrades forcing us to restart the apache
server.

On investigation it is found from the mod_jk.log that a apache child process
serving a user request does not get reponse from tomcat[jboss] and so it
waits for 2 hours and retries 3 times. No clue as why it waits for 2 hours
and where is this configured.

To resolve this thought of using the socket_timeout property setting it to
worker.abc.socket_timeout=600 i.e., 10 mintues. It works fine for apache
running on windows but does not work for apache running on Linux/ Solaris.

Any clue as why this property is not working on Linux/ Solaris.
