Apache2 doesn't start up

Hi,

I got a big problem. I've got a vServer running Debian 3.1 including
Apache2. It ran without problems. But now I added some DirectoyListing
in the apache2.conf and had to restart it. So I tried apache2ctl
restart, but nothing happend. The programm didn't terminate and the
apache didn't restart. So I pushed ^-C to stop apache2ctl. Then I killed
the Apache by using the kill-command and after that tried to start it.
But neither apache2ctl start nor apache2 -k start were successful. It
allways looks like this:

vs159119:~# apache2ctl start

and that's it, till i stop it by pressing ^-C

Output of ps -e f while apache2ctl is running:

28612 pts/0 Ss 0:00 | \_ -bash
20422 pts/0 S+ 0:00 | \_ /bin/sh /usr/sbin/apache2ctl start
20516 pts/0 S+ 0:00 | \_ /usr/sbin/apache2 -k start

It's the same, when I type apache2 -k something or apache2 or apache2 -t
and so on, but some special options are ok, like -l, -L, -v, -V, -h and
things like that.

I tried to find the error, but wasn't succesful. There's nothing in the
error.log, an update from 2.0.52 to 2.0.54 didn't change a thing.

Thanks for solutions
