Hi All,
We've been running Tomcat for over 6 months on several farmed servers
(linux) without any major problems. We serve out hundreds of thousands of
JSPs a day and some days it crosses millions. We normally do monthly
reboots of the server, but we do restart Apache every hour and only restart
Tomcat when releasing new builds.
I have seen the servers come to a halt, but this is usually caused by our
db connections being held up. When that happens the Tomcat processes
escalate > 400, and then the Apache processes escalate > 500. This brings
the machine to its knees. Fixing db bottlenecks and taking all static
content off the application servers fixed those problems.
Maybe we've just been lucky.......
