When I send SIGTERM to tomcat, I actually do get 1) these messages in my catalina.out
Mar 8, 2010 2:46:05 PM org.apache.catalina.core.StandardService stop INFO: Stopping service Catalina and, 2) my servlets destroy() methods do get called. That’s why I suspect that even SIGTERM seems to bring tomcat down in an orderly manner. I should mention that I am on a linux platform, running tomcat 6.0.20. As to why on a busy system, "catalina.sh stop" takes longer I really don't have the details. All I can say is that sometimes I don't even see the above messages for first 20-25 seconds. Could it be because "catalina.sh stop" has to start another JVM and then send a "stop" message to tomcat process over a local loop interface and on a busy system, both of these require resources which may not be available. -Ajay -----Original Message----- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: Monday, March 08, 2010 1:33 PM To: Tomcat Users List Subject: Re: tomcat shutdown: catalina.sh STOP vs SIGTERM -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ajay, On 3/8/2010 12:53 PM, Aggarwal, Ajay wrote: > Sometimes on a busy system I have seen that "catalina.sh stop" does take > a long time to shutdown tomcat. You might want to investigate why this is happening: my Tomcat instances (we have 4 in production) take only a few seconds to shut down completely. > We are running another "monitoring > service" on the system that monitors tomcat and few other system > services.

I tried issuing a SIGTERM to my JVM/Tomcat process running in development, and I got some messages in the app log file that indicated that the webapp was coming down. But, I didn't get any "shutting down" messages in catalina.out which leads me to believe that the shutdown wasn't entirely clean. > It does seem to bring > tomcat down in an orderly manner and much faster than "catalina.sh > stop". Well, definitely faster, but I'm not sure about orderly: you should check to see what things aren't stopping and determine if they are potentially disastrous it TERMinated. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuVQt8ACgkQ9CaO5/Lv0PD8LgCdFbaGLq1nfsqJJb4dbAsKY8hT lFEAoLUQHVzXZ9KnrQ79ExupS4cyKDfD =vn8E -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
