No changes regarding firewall or load balancers. Tomcat and apache live
on the same machine in this case.

maybe done last night between apache and tomcat? Can you access tomcat apps
bypassing apache?
There are, what appears to be three tomcat instances on this machine.
One using 8080, one on 8180 and the other 8280. I cannot connect to any
of these but the only one I care about is the one on 8180
Can you telnet to tomcat server on the tomcat port from
the apache?
I have tried telneting to the host on all ports defined in server.xml
and I can telnet to 8105 and 8205, the SHUTDOWN ports, but not 8005, and
none of the others. The connector ports for this instance, the one I am
concerned with are 8180 and 8443. The AJP connector port is 8010
Any errors in the tomcat log? Have you tried restarting tomcat?
I have tried and thought I was successful but I am now getting:

when I try to shut it down.
I hope I am giving you useful information. As I said, I am not an
experienced tomcat admin. I inherited this site and am just trying to
learn. Wish ?I didn't have to learn under these circumstances.
Thanks

Not sure what happened here. The app was working just fine until today. I
am getting a 503 Service temporarily unavailable error when trying to
connect to a tomcat site using Apache as the front end and mod_jk

using:netstat -atp | grep java. I see no errors in the message logs ( we are
on CentOS by the way ) but I do see:

in the mod_jk.log file. Apache is running. I am stumped but really need to
get this back running if anyone out there is more experienced at tomcat and
apache connectors than I am, which wouldn't take much ;-)
Cheers,
Dave
