Description Jaco Kroon 2004-01-28 23:52:07 UTC

When you have meny virtual hosts apache can take a while to shut down causing
the restart script to start apache again before apache has properly shut down.
This is almost a non-issue for most people, but alas, there are always those
who would like things to happen correctly.

Reproducible: Sometimes
Steps to Reproduce:
1.  /etc/init.d/apache2 restart
2.
3.

Actual Results:  
It doesn't always actually restart apache, complaining about port 80 being in use.

Expected Results:  
Should have waited for apache to shut down properly and then start apache again

fix for apache restart problem

The above should fix it (well, permitting apache doesn't take more than 5
seconds to shut down - I've never seen this).

Also, why are we using start-stop-daemon in the first place when a utility like
apache2ctl already exists to do all this for us?  I mean, in start you can
simply
call apache2ctl start, in stop apache2ctl stop, the same applies to restart and
reload.

I have seen more than a minute on our web server.  It all depends on system load...
