Instead of using that kill line in postrotate (which, based upon a
perusal of the apache2 and apache2ctl manpages, appears to be
deprecated), invoke /etc/init.d/apache2 restart.
Editing /etc/conf.d/apache2 may do nothing if you're working directly
under the covers as you are above.
Incidentally, I believe the problem may be that you're doing a graceful
restart, which does not necessarily close the log files immediately
(and, if the system is busy, probably does not.)
So, um, this prerotate thing you do - you're copying the log file before
it is static? You realize that you may not get the full log file that
way, right?
