Page fault

[Marian Dobre]

Hi,

I'm having a problem with my freebsd 5.1 RELEASE box. After the last 
cvsup I keep getting page fault errors.
Could it be a software problem or maybe the memory is bad ?
This is the error im seeing on the console

Fataltrap 12: page fault while in kernel mode
fault virtual address = x0c
fault code = supervisor read, page not present
...................................................................
current process = 12 ( swi: net )
trap number = 12
panic: page fault

Any idea what could cause this error ?
This is the output of uname -a
