>Description:
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 0x0, 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.
