Or install some Perl Modules? Err -- yes. Both of those things. You need perl-5.8.5 and you'll need to install the databases/p5-BerkeleyDB module. I don't think those two requirements are anything to do with the material cause of the crash though -- the example code is just from something I was developing -- actually, now developed in a way that avoids knocking over my machine, and released: see http://www.infracaninophile.co.uk/portindex/ I have a feeling that the problem is triggered by code like the following in perl: sub foo { my $bar =3D {}; $bar->{blurlf} =3D "gronk"; return $bar; } and repeat that sort of thing a few thousand times. If instead of having $bar as a 'my' variable, you pass it into the function it seems to avoid the problem. Nb. as that code is in essence the standard way of instantiating a perl object, that's pretty bad.
