Hi all, I am testing the kernel 3.2.1 (32-bit) XFS filesystem on a 1 TB LVM logical volume. The volume currently has 3653816 files, 3655726 used inodes and 782G free space. When the volume is mounted, quotacheck starts up and after about 5 minutes the oom-killer is triggered and starts killing processes. From the message log, it looks like the system is running out of Normal memory. After a while I see the following messages after which I power cycle the system: XFS: possible memory allocation deadlock in kmem_zone_alloc (mode: 0x2d0) XFS: possible memory allocation deadlock in xfs_buf_allocate_memory (mode: 0x250) The kernel is configured for 2G/2G memory split. I tried setting vm.overcommit_memory to 2 and vm.overcommit_ratio first to 80 and then 50 and that did not help. The server has an Intel Quad core Xeon CPU X3450 @ 2.67GHz with 4 GB RAM. The swap partition is 8GB in size. Is this a known issue and if so, is a patch available? Is there a kernel configuration parameter that can be adjusted to fix this? Do let me know if you need additional information about the test setup or kernel configuration. Thanks for your help.
