Subject: tomcat crashing and being restarted by a script on the 3 webservices machines

Date: Nov 30, 2009 03:51 PM

Gabriel, you were wondering why they crash.
I'm not sure what to tell you but here's some info:

I have a script
(/usr/local/apps/jakarta-tomcat-5.5.9/logs/check_restart_dead_tomcat.sh)
that currently checks via cron 
every 10 minutes to see if there's a tomcat process running - if not, it
starts tomcat. 
If it restarts or if it's on the hour it writes a note to a log
(/usr/local/apps/jakarta-tomcat-5.5.9/logs/check_restart_dead_tomcat.log
)

Today, for example:

webservices-1 - tomcat restarted 4 times 
	Mon Nov 30 11:20:02 EST 2009 restarting tomcat
	Mon Nov 30 12:30:02 EST 2009 restarting tomcat
	Mon Nov 30 13:35:01 EST 2009 restarting tomcat
	Mon Nov 30 13:45:01 EST 2009 restarting tomcat

webservices-2 - tomcat restarted 0 times
webservices-3 - tomcat restarted 1 times

I've been looking for something in catalina.out or other logs for info
on what's going on when a restart happens.
I've found some hs_err_pid files, but they don't match up with the
restarts.

For example, this one hs_err_pid32185.log on webservices-3 is from
11/20, there's no file from today.

But in case it's useful here it is:
