Subject Re: tomcat unexpected shutdown
Date Thu, 19 Dec 2013 02:47:41 GMT
Thanks, your response

I found the problem why tomcat unexpectly shutdown.it is not a
system.exit() method and kill command and shutdown port

The problem is that the opertator using his own script to start tomcat.

the script is like this

=================================
#!/bin/bash
./tomcat_path/bin/startup.sh
tail -f /tomcat_path/logs/catalina.2013-12-19.log

=================================

tomcat shutdown normally progress when the operator excuete a script and
close the terminal window that he excueted  (terminal is secureCRT, putty,x
Xshell)

"The Ctrl + c" input is not a shutdown condition, but close the terminl
unexpectly shutdown the tomcat.

why this script cause the shutdown problem?

thanks anyway
