Subject Re: Tomcat 5.0.28 exiting randomly
Date Thu, 13 Jan 2005 11:31:19 GMT
Hi Greg,

Until you can track down the culprit, you may want to look into 
the security manager to disallow System.exit calls.
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/security-manager-howto.html

Are you using any 3rd party jar files?
If it's in your code, grep should find it in seconds.
