Re: [rrd-users] RRDp.pm error weirdness

well, i've "fixed" it for my purposes by changing RRDp.pm to "return
$ERR = 1" instead of just setting $ERR = 1 when $line matches ^ERROR. for my
immediate purposes this works, but i'm curious if this is a bug or my
misunderstanding of how this is supposed to work.
