Hi Tom,
You'll probably find that you've got a logrotate job in your crontab. This is
a nice tidy way of keeping your log files tidy.
What this does is scrolls down your logfiles, e.g. .3 becomes .4, .2 to .3, .1
to .2 and your current logfile becomes .1. It then creates a new empty log.
However, Apache has an open file handle that is still pointing to the old
logfile. Sending a HUP to Apache tells it to do a gracefull restart which
amongst other things makes it close/reopen the log file.
