Bug#511103: apache2-mpm-prefork: SEGV NOT fixed in 2.2.11-2 either

Package: apache2-mpm-prefork
Version: 2.2.11-2
Followup-For: Bug #511103


Not only is it NOT fixed, but it's so bad that it takes the machine down
with it, *requiring* a reboot. I've had to do this 4 times today alone.
Almost every single time I go to restart apache, it crashes this way.

BTW, the load average on the machine also skyrockets, even though
almost nothing is running. I tried running iotop, but my kerneldoesn't
support it seems (that's what it told me, more or less).

I just updated to Lenny from an Etch install, to beat the rush so to speak,
and now I'm re-considering that, and downgrading everything to Etch.

I even recompiled my kernel to see if that would help anything, and of
course it didn't. If I'm coming across as pissed off, I am, but I seriously
do not want to come at you the wrong way. It's just extremely frustrating.

Yesterday on #debian on freenode, it was suggested to me to lower my worker
count to as low as I could get it. I haven't done that, though I doubt
it'll help much. I'll try it, but I'm not holding my breath.

5.66 5.82 4.73
pretty much the only active process at the moment:
/usr/sbin/logrotate /etc/logrotate.conf

I'd call it odd, wouldn't you? ;)

thanks
simon
