Thanks for the tips Chris. I had tried AJP PING/PONG options which worked for a while, but not consistently. Seems like a better solution would be to work with network folks regarding firewall config.
Just want to mention a nice Perl script that I found during debugging: http://www.perlmonks.org/?node_id=766945 , useful for sending AJP ping requests to Tomcat independent of web server. -- Shantanu.
