Bug#257414: Server processes not stopped when uninstalled/purged

[Frans Pop <aragorn@tiscali.nl>]

Package: apache2-mpm-worker
Version: 2.0.49-1
Severity: important

I installed this variant of apache2 on a laptop to act as a local server, but 
this did not work when the laptop was not connected to a network (DNS server 
not available so localhost would not be resolved so I was denied access to 
directories protected with 'Access allow localhost').

Anyway, I decided to switch to boa (also because apache is a bit heavy for my 
purpose).
In dselect I indicated all installed apache2 packages should be purged and boa 
installed. During installation I received an error during postinst of boa.

After some research, I discovered that the apache2 server processes were still 
running, even though apache2 had been uninstalled. I manually killed these 
processes (and after that the postinst of boa succeeded without problems).

Processes still running after uninstall (from 'ps alx'):

Output from 'dpkg -l apache2*' after uninstall:
