Hi Pete,

Thanks for the reply.  I looked into it and have found the correct package to 
install on Debian apache2-mpm-prefork.  I checked the old server and it was 
using the prefork mpm as well.  It was also pointed out that version of apache 
is 3 years old.  I attempted to build from source but didn't get very far so 
abandoned that idea.  It's behaving as I'm used to now and as it's for a 
development box that will see small amounts of traffic I think it will do what 
I need it to.  Thanks for your help.

Regards

Colin

The behaviour you are describing is the standard behaviour with mod_cgid. My 
guess is that when you performed the upgrade you moved from a prefork MPM to a 
threaded MPM and therefore by default from mod_cgi to mod_cgid.

There is not, to my knowledge, any simple way of over-riding this logging 
behaviour within mod_cgid. However, the benefits of a threaded MPM often 
outweigh this drawback. If you decide that you would prefer to return to a 
prefork MPM you should check with your distro as to the recommended way to 
achieve that. I do not use Debian 7 so cannot advise on that score.

Good luck,

Pete
