What you have here is the classic LogRolling Problem.
what you want is a Signal Handler -
$SIG{HUP} = \&rollLog;
sub rollLog {
# our premise is that the log file was already open
}
an illustration is at:

you might want to think about doing this as a real daemon

I understand that in the last five seconds - a lot of grot
can roll in and it may take an arbitrarily long amount of
time to get back to grovelling that log file - but have
you thought about upping the sleeptime to allow other
processes on the host a chance to use the system ???
