Hi Monks,

Next to an Apache/mod_perl combo I'm running a small daemon for continuous number crunching.

Both Apache and the daemon are very related.

The daemon is currently started and stopped through its own "daemonctl" script.

Now I'm searching for a solution to get the small daemon started and stoppen through Apache.
Starting is quite easy through "startup.pl" and a few other ways.
But to get it stopped is not that easy!

The only solution that came to my mind was to check the pid file of the Apache whenever the daemon reaches the end of its main loop. (not very elegant)
A wrapper script for both "apachectl" and "daemonctl" is ugly too.

I checked a lot of documentations/books/tutorials but found no direct way like a special cleanup/shutdown handler or the like.
Think i saw a note somewhere that Apache itself has no such handler.

Any suggestions for a clean solution?

(No matter which version of apache/mod_perl)
