And for one of my servers (8.2-PRERELEASE/amd64 with 4GB RAM) I just cannot
obtain crashdump,
it cannot finish to write it. For example, it happened an hour ago:
Fatal trap 12: page fault while in kernel mode
cpuid = 2; apic id = 04
fault virtual address = 0x200000040
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff803cc979
stack pointer = 0x28:0xffffff80ec09c630
frame pointer = 0x28:0xffffff80ec09c6b0
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 = 32220 (mpd5)
trap number = 12
panic: page fault
cpuid = 2
Uptime: 23h45m12s
Physical memory: 4080 MB
Dumping 564 MB:panic: bufwrite: buffer is not busy???
cpuid = 2
Uptime: 23h45m13s
Automatic reboot in 15 seconds - press a key on the console to abort
Another time it panices and could not finish to write crashdump another way:
Fatal trap 12: page fault while in kernel mode
cpuid = 3; apic id = 06
fault virtual address = 0x60
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff803e4baf
stack pointer = 0x28:0xffffff80e96d1a20
frame pointer = 0x28:0xffffff80e96d1a30
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 = 0 (dummynet)
trap number = 12
panic: page fault
cpuid = 3
Uptime: 2d2h33m4s
Dumping 4087 MB (3 chunks)
chunk 0: 1MB (150 pages)Sleeping thread (tid 100100, pid 0) owns a
non-sleepable lock
