I am running apache-tomcat-5.5.15 on three boxes 2 rh9 and one fedora
4. and they are clustered together
I am seeing problems where apache can not longer talk to tomcat.
if anyone can point me on how to debug this please help, i am not sure
what else i should include as far a conf setups, so please let me know
what other details i need to supply so you guys can help
Thanks
in the log files at the time of the failure i see the following
catalina.out ( i will see a bunch of these)

When this error happens, are you able to issue the command
1. to see if tomcat is listening,
netstat -na |grep 8009 |grep LISTEN
2. if yes, try to connect to the socket
"telnet localhost 8009"
on the box you see the error, this will tell you if the server socket is
alright.

The Both the apache and tomcat are on the same server and the
workers.properties connects via localhost
Thanks

Hi Randy, if Apache cannot talk to Tomcat, then its not because of the
clustering. The first error in catalina.out, is just a result of
replication keep alive sessions getting closed, I will fix the code that
generates that error so that it doesn't log as an error.
do you have a firewall or anything of that kind between apache and tomcat?
