Message-ID: <20071029221645.eiseeshu@trusted.lncsa.com> Date: Mon, 29 Oct 2007 22:18:18 +0100 From: Laurent Caron <lcaron@...sa.com> To: linux-kernel@...r.kernel.org Subject: Crash with XFS on top of DRBD (DRBD 8.0.6 svn / Kernel 2.6.22) Hi, I'm back with my crash, oomkiller..... problems on my DRBD cluster of 2 servers. I compiled a 2.6.22 kernel with slab/slab debugging turned on. Here is the last oom-killer message I got on that server. I couldn't wait until a crash since a lot of users are working on it: ----------------------------------------------- kernel: procmail invoked oom-killer: gfp_mask=0xd0, order=1, oomkilladj=0 kernel: [<c0147dbe>] out_of_memory+0x69/0x197 kernel: [<c01492e1>] __alloc_pages+0x20a/0x294 kernel: [<c0149397>] __get_free_pages+0x2c/0x3a kernel: [<c011ba87>] copy_process+0xa4/0x102d kernel: [<c012aff2>] alloc_pid+0x16/0x240 kernel: [<c016048d>] kmem_cache_alloc+0x80/0x8a kernel: [<c012aff2>] alloc_pid+0x16/0x240 kernel: [<c011cc57>] do_fork+0x9a/0x1c2 kernel: [<c01021d1>] sys_clone+0x36/0x3b kernel: [<c0103cb2>] sysenter_past_esp+0x6b/0xa1 kernel: ======================= kernel: Mem-info: kernel: DMA per-cpu: kernel: CPU 0: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 1: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 2: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 3: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 4: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 5: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 6: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: CPU 7: Hot: hi: 0, btch: 1 usd: 0 Cold: hi: 0, btch: 1 usd: 0 kernel: Normal per-cpu: kernel: CPU 0: Hot: hi: 186, btch: 31 usd: 63 Cold: hi: 62, btch: 15 usd: 51 kernel: CPU 1: Hot: hi: 186, btch: 31 usd: 97 Cold: hi: 62, btch: 15 usd: 54 kernel: CPU 2: Hot: hi: 186, btch: 31 usd: 26 Cold: hi: 62, btch: 15 usd: 47 kernel: CPU 3: Hot: hi: 186, btch: 31 usd: 8 Cold: hi: 62, btch: 15 usd: 61 kernel: CPU 4: Hot: hi: 186, btch: 31 usd: 18 Cold: hi: 62, btch: 15 usd: 53 kernel: CPU 5: Hot: hi: 186, btch: 31 usd: 0 Cold: hi: 62, btch: 15 usd: 60 kernel: CPU 6: Hot: hi: 186, btch: 31 usd: 6 Cold: hi: 62, btch: 15 usd: 57 kernel: CPU 7: Hot: hi: 186, btch: 31 usd: 28 Cold: hi: 62, btch: 15 usd: 59 kernel: HighMem per-cpu: kernel: CPU 0: Hot: hi: 186, btch: 31 usd: 98 Cold: hi: 62, btch: 15 usd: 8 kernel: CPU 1: Hot: hi: 186, btch: 31 usd: 7 Cold: hi: 62, btch: 15 usd: 12 kernel: CPU 2: Hot: hi: 186, btch: 31 usd: 85 Cold: hi: 62, btch: 15 usd: 4 kernel: CPU 3: Hot: hi: 186, btch: 31 usd: 72 Cold: hi: 62, btch: 15 usd: 0 kernel: CPU 4: Hot: hi: 186, btch: 31 usd: 21 Cold: hi: 62, btch: 15 usd: 6 kernel: CPU 5: Hot: hi: 186, btch: 31 usd: 19 Cold: hi: 62, btch: 15 usd: 12 kernel: CPU 6: Hot: hi: 186, btch: 31 usd: 175 Cold: hi: 62, btch: 15 usd: 12 kernel: CPU 7: Hot: hi: 186, btch: 31 usd: 137 Cold: hi: 62, btch: 15 usd: 2 kernel: Active:381850 inactive:9157 dirty:256 writeback:97 unstable:0 kernel: free:2519061 slab:22044 mapped:7487 pagetables:2163 bounce:0 kernel: DMA free:3564kB min:68kB low:84kB high:100kB active:0kB inactive:0kB present:16256kB pages_scanned:0 all_unreclaimable? yes kernel: lowmem_reserve[]: 0 873 12938 kernel: Normal free:7756kB min:3744kB low:4680kB high:5616kB active:116kB inactive:0kB present:894080kB pages_scanned:192 all_unreclaimable? yes kernel: lowmem_reserve[]: 0 0 96520 kernel: HighMem free:10064924kB min:512kB low:13456kB high:26404kB active:1527284kB inactive:36804kB present:12354560kB pages_scanned:0 all_unreclaimable? no kernel: lowmem_reserve[]: 0 0 0 kernel: DMA: 9*4kB 15*8kB 3*16kB 1*32kB 0*64kB 0*128kB 1*256kB 0*512kB 1*1024kB 1*2048kB 0*4096kB = 3564kB kernel: Normal: 1495*4kB 10*8kB 1*16kB 0*32kB 1*64kB 1*128kB 0*256kB 1*512kB 1*1024kB 0*2048kB 0*4096kB = 7804kB kernel: HighMem: 39234*4kB 109305*8kB 80630*16kB 52420*32kB 27267*64kB 9904*128kB 2822*256kB 871*512kB 377*1024kB 218*2048kB 257*4096kB = 10065264kB kernel: Swap cache: add 43, delete 42, find 0/0, race 0+0 kernel: Free swap = 393204kB kernel: Total swap = 393208kB kernel: Free swap: 393204kB kernel: 3342335 pages of RAM kernel: 3112959 pages of HIGHMEM kernel: 224356 reserved pages kernel: 221558 pages shared kernel: 1 pages swap cached kernel: 256 pages dirty kernel: 97 pages writeback kernel: 7487 pages mapped kernel: 22044 pages slab kernel: 2163 pages pagetables kernel: Out of memory: kill process 12069 (slapd) score 62386 or a child kernel: Killed process 12069 (slapd) --------------------------------------------- Do anyone have any clue about what's happening ?
