Subject Re: Tomcat shutdowns unexpectedly - Please help
Date Tue, 11 Jul 2006 13:45:58 GMT

I hope I get it correctly, the Tomcat shutdowns when it is ideal. That means no one is working
with it and there is no connection to it.
If I assume correct and this is the case, please let me know if this shutdown happens when
there are some connections to it.
We had this problem once with Apache and OracleAS, the OracleAS shouted down itself when it
does not received any requests (made a suicide!) We end up writing a small program which was
connected to Tomcat every 10 min and requested a dummy page. It solved it.

P.S: Did you configure your Tomcat with Apache?

Hope it helps you!

If the service is crashing on startup(misconfigured JVM, startup jars missing) then check
the jakarta_service_YYYYMMDD.log
