Message-ID: <20030410163857.GB19129@zip.com.au> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.28i Organisation: Furball Inc. Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Buggered if I know what triggered this exactly. At the time I was abusing the living snot out of the system by compiling mplayer twice, compiling the kernel, getting mozilla to load 50 or so pages and running a program that allocs ram until it's oom-killed a few times. These happened well after the last running of the memory eater and the slab/tcp error happened 10 mins before the ext3/block error. The slab/tcp happened just before the first of the mplayer compiles finished. The ext3/block happened just before the 2nd mplayer compile finished. Through both mplayer compiles the kernel was compiling and mozilla was trying to do its thing. Also, mplayer compiles were happening on the same partition as each other but on a different partition to the kernel. I think I'll run a fs check now... :) Slab corruption: start=ce6130c4, expend=ce6131f3, problemat=ce613128 Last user: [](destroy_conntrack+0x9c/0xac) Data: ****************************************************************************************************28 31 61 CE 28 31 61 CE ***************************************************************************************************************************************************************************************************A5 Next: 71 F0 2C .78 FF 32 C0 71 F0 2C .******************** slab error in check_poison_obj(): cache `ip_conntrack': object was modified after freeing Call Trace: [] __slab_error+0x21/0x28 [] check_poison_obj+0x174/0x180 [] kmem_cache_alloc+0x8d/0x128 [] init_conntrack+0xcf/0x310 [] init_conntrack+0xcf/0x310 [] ip_conntrack_in+0x138/0x274 [] shmem_readlink+0x64/0xc0 [] ip_conntrack_local+0x52/0x58 [] dst_output+0x0/0x28 [] nf_iterate+0x34/0x88 [] dst_output+0x0/0x28 [] nf_hook_slow+0xb6/0x140 [] dst_output+0x0/0x28 [] ip_queue_xmit+0x400/0x458 [] dst_output+0x0/0x28 [] error_code+0x2d/0x38 [] tcp_v4_send_check+0x6e/0xb0 [] tcp_transmit_skb+0x424/0x588 [] tcp_transmit_skb+0x4d8/0x588 [] tcp_connect+0x3c3/0x45c [] tcp_v4_connect+0x432/0x4f8 [] inet_stream_connect+0xd7/0x1f0 [] sys_connect+0x5f/0x84 [] sock_map_fd+0xc2/0x120 [] sock_map_fd+0x110/0x120 [] sock_create+0xb4/0xe0 [] sys_socket+0x2e/0x4c [] sys_socketcall+0xa4/0x1c0 [] sys_munmap+0x44/0x64 [] syscall_call+0x7/0xb buffer layer error at fs/buffer.c:127 Call Trace: [] __buffer_error+0x2a/0x30 [] __wait_on_buffer+0x66/0xb0 [] autoremove_wake_function+0x0/0x3c [] autoremove_wake_function+0x0/0x3c [] __block_prepare_write+0x2a3/0x3b0 [] block_prepare_write+0x20/0x3c [] ext3_get_block+0x0/0x68 [] ext3_prepare_write+0x48/0xe0 [] ext3_get_block+0x0/0x68 [] generic_file_aio_write_nolock+0x5e2/0x9c8 [] generic_file_aio_write+0x7b/0x94 [] ext3_file_write+0x2e/0xc4 [] do_sync_write+0x7f/0xb0 [] do_rw_disk+0x440/0x67c [] update_process_times+0x2c/0x38 [] update_wall_time+0xe/0x38 [] do_timer+0x4d/0xd4 [] generic_file_llseek+0x31/0xd0 [] vfs_write+0x9e/0xd0 [] sys_write+0x2a/0x40 [] syscall_call+0x7/0xb -- Martin's distress was in contrast to the bitter satisfaction of some of his fellow marines as they surveyed the scene. "The Iraqis are sick people and we are the chemotherapy," said Corporal Ryan Dupre. "I am starting to hate this country. Wait till I get hold of a friggin' Iraqi. No, I won't get hold of one. I'll just kill him." - http://www.informationclearinghouse.info/article2479.htm
