Subject: Re: mod_jserv/5755: mod_jserv and httpd -HUP restarting problem

 Instead of running 'killall -HUP httpd', try sending HUP to only the
 parent httpd process.  (If you used the RedHat RPM, IIRC this would be: 
 "kill -HUP `cat /var/run/httpd.pid`" -- though you may need to change the
 file location -- or perhaps something like '/etc/rc.d/apache reload'.)  If
 you send killall -HUP, the child httpd processes will recieve two HUP
 signals.  That may (or may not) be sufficient to cause problems of some
 sort or another with JServ ...
 Generally, the error which you've described occurs when you're using
 automatic mode, and mod_jserv fails to tell the JVM to terminate; I'm not
 sure what could have changed between 1.0 and 1.1, but it's certainly
 possible that something changed which would affect timing slightly. 
 You can, of course, turn off automatic mode, which would solve this
 problem -- but then you need to do process management for the JVM
 good luck --
