How can we help you? You don't give us any details...version/distro of Linux? Tomcat? ANY log messages (not just syslog, have you checked both the apache and tomcat logs?). The chkconfig will only set a service to start at boot time or when the server enters that runlevel. It won't automatically restart a process.

If the only thing crashing is tomcat, and you can restart tomcat manually after a crash, then there has to be a log message SOMEWHERE that tells you why it died.

Hi
Frequently im facing out problem of tomcat service getting shut down automatically .

Ditro os:centos 5.4
Tomcat version :6.0.26
chkconfig level i had made made on for 345 level but still the tomcat breaks up frequently .i never getting out any error about the shutdown in tomcat logs.

Ok...did you read the reply above???

Unless you can identify WHAT is causing the crash, there's no way of anyone being able to help you. There is some application/script/SOMETHING, somewhere, causing the problem(s). Identify what, then debug it...can't get much simpler than that. All you've told us is your tomcat crashes...which gives us NOTHING to go on.

Ok...you posted a chunk of your tomcat logs, and hijacked someone elses thread with a question too. I'll take it that the version/distro of Linux and the version of tomcat are what you hijacked that other thread with.

However, you STILL don't tell us WHAT web application is causing this, who wrote it, etc. Looks like it was poorly written, and tells you that the JDBC driver wasn't unregistered when the app stopped. Whoever wrote the app probably has more work to do on it...why don't you contact the developer? Also, again...have you bothered to check Google for these errors??? Amazingly, there appears to be over 5,000 hits, along with solutions....

http://wiki.apache.org/tomcat/MemoryLeakProtection

...and one is even on this very site, detailing a bug in 6.0.26 in Tomcat....

@jayakumar01: please (and I mean please) don't add confusion by replying in place of someone from your team or don't post in the same thread with two different accounts whatever be the case. In the meanwhile I've merged two strictly related threads of yours into this one, but please (and I repeat please) refrain from this behaviour in the future. Nuff' said!
