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,
