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

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 setup.

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 is this property not working on Linux/ Solaris.
