Date: Sat, 5 Jun 2010 10:46:03 +1000 From: andrew hendry <andrew.hendry@...il.com> To: linux-kernel <linux-kernel@...r.kernel.org> Subject: 2.6.35-rc1 system oom, many processes killed but memory not free I left a 2.6.35-rc1 system, ubuntu 10.4/64 building randconfigs in a ramdisk overnight. /dev/ram0 9842848 5141780 4201068 56% /media/ramdisk After about 3 hours oom killer started killing nearly all the processes, but the memory is still not released. Could ramdisk cause this? How can I find out what is still using all the memory? cat /proc/meminfo MemTotal: 8187304 kB MemFree: 231976 kB Buffers: 424 kB Cached: 19728 kB SwapCached: 51144 kB Active: 14056 kB Inactive: 72592 kB Active(anon): 12900 kB Inactive(anon): 53940 kB Active(file): 1156 kB Inactive(file): 18652 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 1986556 kB SwapFree: 1504676 kB Dirty: 0 kB Writeback: 19720 kB AnonPages: 32884 kB Mapped: 4760 kB Shmem: 4 kB Slab: 51652 kB SReclaimable: 28816 kB SUnreclaim: 22836 kB KernelStack: 2880 kB PageTables: 18484 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 6080208 kB Committed_AS: 1133944 kB VmallocTotal: 34359738367 kB VmallocUsed: 350936 kB VmallocChunk: 34359369212 kB HardwareCorrupted: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 7616 kB DirectMap2M: 8372224 kB Active / Total Objects (% used) : 152645 / 170934 (89.3%) Active / Total Slabs (% used) : 3918 / 3918 (100.0%) Active / Total Caches (% used) : 68 / 88 (77.3%) Active / Total Size (% used) : 43995.40K / 49940.66K (88.1%) Minimum / Average / Maximum Object : 0.01K / 0.29K / 16.12K OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 39063 35168 90% 0.55K 1347 29 21552K radix_tree_node 17296 17114 98% 0.17K 376 46 3008K vm_area_struct 2706 1173 43% 0.96K 82 33 2624K ext4_inode_cache 385 377 97% 5.62K 77 5 2464K task_struct 300 299 99% 8.00K 75 4 2400K kmalloc-8192 8820 8265 93% 0.19K 210 42 1680K kmalloc-192 8400 4063 48% 0.19K 200 42 1600K dentry 2268 1624 71% 0.58K 84 27 1344K inode_cache 13617 13617 100% 0.08K 267 51 1068K sysfs_dir_cache 1024 937 91% 1.00K 32 32 1024K kmalloc-1024 14592 9444 64% 0.06K 228 64 912K kmalloc-64 400 372 93% 2.00K 25 16 800K kmalloc-2048 375 326 86% 2.06K 25 15 800K sighand_cache 1000 989 98% 0.79K 25 40 800K shmem_inode_cache 152 140 92% 4.00K 19 8 608K kmalloc-4096 714 711 99% 0.75K 17 42 544K RAW 7280 7280 100% 0.07K 130 56 520K Acpi-ParseExt Jun 5 04:51:58 jaunty kernel: [25913.310588] firefox-bin invoked oom-killer: gfp_mask=0xd0, order=1, oom_adj=0 Jun 5 04:51:58 jaunty kernel: [25913.310591] firefox-bin cpuset=/ mems_allowed=0 Jun 5 04:51:58 jaunty kernel: [25913.310594] Pid: 13275, comm: firefox-bin Not tainted 2.6.35-rc1+ #3 Jun 5 04:51:58 jaunty kernel: [25913.310595] Call Trace: Jun 5 04:51:58 jaunty kernel: [25913.310603] [<ffffffff810ec772>] dump_header+0x72/0x1c0 Jun 5 04:51:58 jaunty kernel: [25913.310608] [<ffffffff8151e5dc>] ?
