Thank you for helping me.     The earlier suggestion of toggling Perl  
Malloc didn't work, nor did syncing sources and installing new kernel  
and new world which is what I did lsat night.

As for kernel settings, I don't have anything in my loader.conf,  and  
I'm not entirely sure how to show things that aren't sysctls, as this  
one doesn't seem to be:

celebrian# sysctl -a | grep kern.maxdsiz
celebrian# sysctl -a | grep kern.defdsiz
celebrian#


(Btw, using Perl Malloc didn't work, nor did syncing sources and  
installing new kernel and new world.)

I'm going to try your settings in loader.conf and see if they work for  
me.
