Description Paul Crawford 2002-02-13 11:20:01 UTC 
I have an automated script running on another machine that starts an FTP session on my FreeBSD server, runs the binary command and executes a put command.  Everytime this script is executed (at 3:00AM) I get the following panic and the FreeBSD server reboots:

Fatal trap 12: page fault while in kernel mode
fault virtual address	= 0x0
fault code		= supervisor write, page not present
instruction pointer	= 0x8:0xc02ddc0b
stack pointer	        = 0x10:0xc6444eb0
frame pointer	        = 0x10:0xc6444acc
code segment		= base rx0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 1315 (sendmail)
interrupt mask		= none
trap number		= 12
panic: page fault

The fault occured in the generic kernel at the following function:
# nm -n /kernel | grep c02ddc
c02ddc60 T vm_map_stack

How-To-Repeat: This is repeated the next time the script is executed.

Is this still reproducable on more recent releases?
