Hi Boris,

Why might the system timer do this? I am confused. The thing that ended 
up fixing it was completely rebuilding /usr/src (deleting the dir and 
installing the system sources via csup again)

It's a new computer so perhaps there is some compatibility problem or 
fault with the machine? During a couple of port builds, I noticed a few 
processes relating to the build of a port had died with signal 10 in 
dmesg (bus error i think this means), and during a build of apache, 
something called confcheck had died with signal 12.

I ran memtest86 on this system for about 6 hours and after about 20 
passes, no errors reported.
