Bug#607072: apache2-mpm-itk doesn't kill its processes

[Alex Ballas <alex@ballas.org>]

Package: apache2-mpm-itk
Version: 2.2.6-02-1+lenny3+b1
Severity: important

For some reason my apache2 didn't kill the processes of user and they just sat there in sleep mode consuming a 
portition of my memory. There was no traffic to the particular user at that time and "netstat -ntp" was clear. Apache 
access log was also clear and so did error.log. I even tried to disable this site with a2dissite and reloadi apache, 
but still 
the processes were there. when i did "ps aux | grep demo". I got this

demo       528  0.0  5.2 263764 20084 ?        S    10:38   0:00 /usr/sbin/apache2 -k start

The uids didnt change over time.
I cant reproduce this issue. My last access log was clear.(just normal visit traffic from me)
