I've seen that for years.  I always assumed it was because the apache2
stop didn't complete before the apache2 start tried to start when I use
/etc/init.d/apache2 restart.

Instead I do an /etc/init.d/apache2 stop; ps aux | egrep apache until I
see all the threads are gone and then a /etc/init.d/apache2 start

[gentoo-user] apache2 not running (no pid file)

[Grant]

Has anyone else noticed this sort of behavior from apache-2.2.21-r1:

# /etc/init.d/apache2 restart
 * Stopping apache2 ... [ ok ]
 * Starting apache2 ...
 * start-stop-daemon: /usr/sbin/apache2 is already running [ ok ]
# /etc/init.d/apache2 restart
 * apache2 not running (no pid file)
 * Starting apache2 ... [ ok ]

It probably happens about half the time I restart apache2.  Nothing in
/var/log/apache2/error_log besides:

[notice] caught SIGTERM, shutting down
[notice] Apache/2.2.21 (Unix) configured -- resuming normal operations

+1

If there aren't many threads a quick restart will work fine, but if there are 
many threads hanging around then you may be better off to stop, wait, then 
start.

Thanks fellas, that makes perfect sense.  Would it make sense for me
to request a change to the initscript that waits until all threads
have stopped before starting during a restart?

Right now it's dumb in one direction, and I have a feeling that if it 
gets "fixed" we'll overshoot "correct" and wind up dumb in the other 
direction.

Nevertheless, I've been dealing with this for years and would like to 
hear what the devs have to say. So, yeah.
