If you are using 'strict', you must applies '$msg2 = $var' as 'my $msg2 =
$var',
You are highly recomment to use strict, because you won't need to take care
of
this question at all, $msg2 will destroy after the sub/loop, the entire
scope ends
anyway.
For your question :
undef $msg2 ;
or
$msg2 = undef;

to flush out the out. how
$i = 0;
while(<LOGFILE>)
{
$i++;
if ($i > 10)
