This is just a warning message and doesn't stop apache working or not. E=

accf_http should give you a bit of a performance boost under heavy load a=

Try restarting httpd from the command line: /usr/local/etc/rc.d/apache22 =
restart
This will run a configtest and then try and start up apache. Then check
that apache is still running: /usr/local/etc/rc.d/apache22 status
If apache has mysteriously disappeared and there are no messages in log f=
iles,
then it means apache crashed during the startup process soon after daemon=
ising.
That's pretty diagnostic for loading a dynamic module that disagrees with=
it.
At a guess, and given that you've reinstalled all your php modules, I thi=
nk you
may be being hit by the php module load order problem. In that case, run=
ning
php from the command line will probably also segv on you. This is someth=
ing that
has had quite a lot of attention on this list, but there isn't a really g=
ood solution
yet, other than manually reordering the entries in /usr/local/etc/php/ext=
ensions.ini
Also, if you're running eAccelerator, make sure you recompile it at the s=
ame time
you upgrade the main lang/php5 port: eAccelerator will cause Apache to cr=
ash if you
try and run it against a different version of PHP than it was originally =
compiled
for.
Cheers,
Matthew
