But after putting some disk I/O to the system (PowerBook G4) it became unresponsive, I/O wait went up high and I could see that the OOM killer was killing processes. Logging in via SSH was sometimes possible, but the each session was killed shortly after, so I could not do much. The box finally rebooted itself, the logfile recorded something xfs related in the first backtrace, hence I'm cc'ing the xfs list too: du invoked oom-killer: gfp_mask=0x842d0, order=0, oom_adj=0, oom_score_adj=0 Call Trace: [c0009ce4] show_stack+0x70/0x1bc (unreliable) [c008f508] T.528+0x74/0x1cc [c008f734] T.526+0xd4/0x2a0 [c008fb7c] out_of_memory+0x27c/0x360 [c0093b3c] __alloc_pages_nodemask+0x6f8/0x708 [c00c00b4] new_slab+0x244/0x27c [c00c0620] T.879+0x1cc/0x37c [c00c08d0] kmem_cache_alloc+0x100/0x108 [c01cb2b8] kmem_zone_alloc+0xa4/0x114 [c01a7d58] xfs_inode_alloc+0x40/0x13c [c01a8218] xfs_iget+0x258/0x5a0 [c01c922c] xfs_lookup+0xf8/0x114 [c01d70b0] xfs_vn_lookup+0x5c/0xb0 [c00d14c8] d_alloc_and_lookup+0x54/0x90 [c00d1d4c] do_lookup+0x248/0x2bc [c00d33cc] path_lookupat+0xfc/0x8f4 [c00d3bf8] do_path_lookup+0x34/0xac [c00d53e0] user_path_at+0x64/0xb4 [c00ca638] vfs_fstatat+0x58/0xbc [c00ca6c0] sys_fstatat64+0x24/0x50 [c00124f4] ret_from_syscall+0x0/0x38 --- Exception: c01 at 0xff4b050 LR = 0x10008cf8 This is wih today's git (91e8549bde...); full log & .config on: http://nerdbynature.de/bits/2.6.39-rc4/oom/ Thanks, Christian.
