Hi all,
after upgrading of 4 same hardware servers last week from source, I
have a strange behavior on one of them. There occurs a panic
sporadically (several times a day).
I supposed there is a hardware error, but I exchanged the disk between 2
servers and the problem moved to the other server, with the disks. All
the servers runs more or less the same set of software:
- bind
- sendmail
- mysql
- squid
- apache
- haproxy
Recently, I switched off squid and the panic occurs less frequently. As
far as I understand the problem, it should not be a panic of the system,
if there is a user software error.
Here is the list of functioning servers:
- 13.3-STABLE stable/13-n258054-12bd1341d2aa
- 13.3-STABLE stable/13-n258052-7f936b0cba08
- 13.3-STABLE stable/13-n258052-7f936b0cba08
The problematic server is:
- 13.3-STABLE stable/13-n258056-8b5eb0cf6c4f
Here is usual error:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x20
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff806ee100
stack pointer = 0x28:0xfffffe0208d08df0
frame pointer = 0x28:0xfffffe0208d08e00
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = resume, IOPL = 0
current process = 7 (pf purge)
trap number = 12
panic: page fault
cpuid = 0
If you are interested, I can provide a link to the core dumps.
Please, could you provide any hints, where problems could be? Is there
any problem with pf in 13.3-STABLE that I do not realize? Why is not
occurring on the other systems?
Thank you very much.
Regards,
lk
