Apache Seg fault (11)

I have this in my apace error.log:

[Fri Sep 18 08:10:54 2009] [notice] child pid 9178 exit signal Segmentation fault (11)
[Fri Sep 18 08:11:41 2009] [notice] child pid 9187 exit signal Segmentation fault (11)
[Fri Sep 18 08:12:12 2009] [notice] child pid 9204 exit signal Segmentation fault (11)
[Fri Sep 18 08:12:13 2009] [notice] child pid 9202 exit signal Segmentation fault (11)
[Fri Sep 18 08:14:45 2009] [notice] child pid 9251 exit signal Segmentation fault (11)

It started the same day I made an addition to the vhost.conf file. So I reverted back to the original file did a apache2ctl restart. Unfortunately it's still occurring.

Apache seems to be serving pages OK.

Any ideas?

Cheers,

Nathan.

Finally got this fixed. A simple restart of the server stopped the seg faults.
