Hi,
I'm experiencing a serious problem with XFS on 2.6.12-1.1376_FC3smp
The filesystem locks up (no write possible, mysql won't shut down,
impossible to reboot machine from console) while running MySQL under a
high load. The only error messages I can find are:
thales kernel: allocation failed: out of vmalloc space - use
vmalloc=<size> to increase size.
thales kernel: XFS: possible memory allocation deadlock in kmem_alloc
(mode:0x250
I've tried increasing /proc/sys/vm/min_free_kbytes to 16386 without success.
Any ideas? Where should I start looking, what logs, programs/tests can i
run?
The problem does not appear immediately, the shortest time from reboot
to failure has been 4 hours.
Machine config:
Dell 6650 / 4 x P4 Xeon with 12GB ram.
1.5T SCSI disk array / PW220S / Perc 4/DC
running XFS on top of LVM.
