>Description:
I've activated the disk quota into one filesystem (/home), when any user use the popper program (release 2.53) to read his mail the system crash and reboot.
The console show the following message:
Fatal trap 12: page fault while in Kernel mode
fault virtual address = 0x0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xf01bb245
stack pointer = 0x10:0xefbffd58
frame pointer = 0x10:0xefbff0b4
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 = 296 (popper)
interrupt mask =
panic: page fault
>How-To-Repeat:
Activating disk quota (quotaon -v -a) and using popper to read pending mail.
>Fix:
By the momment deactivating disk quota with quotaoff -v -a, the system works fine.
