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.
