We have been running FreeBSD 2.1 on Pentium 200 MHz machine for 
a while now and this is the first time it died like this.  
Below is what kernel logged to the screen:

fault virtual address		= 0x8
fault code			= supervisor read, page not present
instruction pointer		= 0x8:0xf0110580
code segment			= base 0x0, limit 0xfffff, type 0x1b
				  DPL 0, pres 1, def32, gran 1
processor e-flags		= interrupt enabled, resume, IOPL=0
current process			= 13320 (top)
interrupt mask			=

panic: page fault

Any help regarding how to avoid this type of crash is greatly
appreciated.

Thanks.
