bug(s) in FreeBSD Apache2::SizeLimit ?

[Jonathan Vanasco <jv...@2xlp.com>]

note: this is on a machine running freebsd 6.1
i also mistakingly posted this from a not-subscribed address.   
hopefully no one will approve that :)

mp2.02
	I was running mp2.02 on production , and the recent memory usage had  
me to quickly try profiling with apache2::sizelimit (which i haven't  
done in at least 6mos )

	I noticed something very odd-- my shared memory kept increasing, not  
decreasing.  i figured this might be a version issue or something  
with copy_on_write, so I upgraded to mp2.03

mp2.03
	on first run, i got an error about 'bsd_size_check' not being a  
valid function

	sure enough...

		$HOW_BIG_IS_IT = \&bsd_size_check;
		___
		# rss is in KB but ixrss is in BYTES.
		# This is true on at least FreeBSD, OpenBSD, NetBSD
		# Philip M. Gollucci
		sub _bsd_size_check {
			    my @results = BSD::Resource::getrusage();
			    my $max_rss   = $results[2];
			    my $max_ixrss = int ( $results[3] / 1024 );
		    return ( $max_rss, $max_ixrss );
		}

	i renamed the function , and my shared occasionally increases, but  
now its 1,2,3,4,5,6

so

	a) the function is named wrong in Apache2::SizeLimit
	b) is there any chance its broke?  i'm kind of amazed that i'm  
possibly only sharing a few bytes.
		1_ perhaps ixrss is no longer in bytes on the 6.1+ branches ?
		2_ why would shared mem go up ?  shouldn't it be going down ?  my  
base mem never seems to go up more than a few bytes, but shared  
skyrockets

i'm using the 'X' handler method on the Apache2::SizeLimit docs to  
profile the sizes in this case.
