Freebsd 6.2 panic

[didier derny]

I  have some machines running php/mysql/postfix
from time to time the computers running FreeBSD 6,2
crashes with the following messages

fatal trap 12:page fault while in kernel mode
cpuid=0; apic id=00
fault virtual address = 0x104
fault code = supervisor read, page not present
instruction pointer= 0x20:0xc066c731

Automatic rebbot in 15 second - press a key on the console to abort

does anyone has an idea on what I can do to solve this problem ?

thanks for your help
