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
