If your webapp creates non-daemon threads, then the JVM might never shut down. You can find that out quite easily: just stop Tomcat in the usual way (i.e. without using "kill" in that script) and see if the JVM process completes after a few seconds (how long you should wait depends entirely on how much work your webapp does on shutdown). If it doesn't stop after a while, take a thread dump to see what threads are still running. If there are any non-daemon threads running, they'll be labelled as such and you can try to trace their origin. It might be that your server requires the use of 'kill' -- that would be too bad. Of course, it would be better to use a script that calls catalina.sh with the "-force" option instead of modifying the script to ALWAYS force the shutdown. So, you can still use the upgraded scripts and enable forcing shutdown if you want. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk6d860ACgkQ9CaO5/Lv0PBMjwCffUUlg9d936eyXPy7UZb04uJL sfQAn1+XIPlmw3Y/hTUsMgOxwvuyB0+6 =ajc9 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
