9.2-RELEASE + memcached = page fault

[Eugene Mitrofanov]

Hello

after upgrading to 9.2-release i can see periodical page faults. advises welcome.

examples:

1.

Fatal trap 12: page fault while in kernel mode
cpuid = 5; apic id = 22
fault virtual address   = 0x18
fault code              = supervisor read data, page not present
instruction pointer     = 0x20:0xffffffff8051095c
stack pointer           = 0x28:0xffffff88a9d77800
frame pointer           = 0x28:0xffffff88a9d77810
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 1704 (memcached)
trap number             = 12
panic: page fault
cpuid = 5
Uptime: 2d23h33m33s

2.

Unread portion of the kernel message buffer:
stack pointer           = 0x28:0xffffff88a9b70800
frame pointer           = 0x28:0xffffff88a9b70810
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 2023 (memcached)
trap number             = 12
panic: page fault
cpuid = 4
Uptime: 1d10h59m7s

good luck
