(some kind of kernel bug?) Dear developers, This is one of my productive servers, wich suddenly starts to freeze (crash) some weeks before. I have done all what i can, (i think) please somebody give to me some suggestion: Mar 24 19:22:28 alfa kernel: BUG: Bad page map in process httpd pte:2bf1e025 pmd:1535b5067 Mar 24 19:22:28 alfa kernel: page:ffffea0000f1b250 flags:4000000000000404 count:1 mapcount:-1 mapping:(null) index:0 Mar 24 19:22:28 alfa kernel: addr:00000037b4008000 vm_flags:08000875 anon_vma:(null) mapping:ffff88022b5d25a8 index:8 Mar 24 19:22:28 alfa kernel: vma->vm_ops->fault: filemap_fault+0x0/0x34d Mar 24 19:22:28 alfa kernel: vma->vm_file->f_op->mmap: xfs_file_mmap+0x0/0x33 Mar 24 19:22:28 alfa kernel: Pid: 7512, comm: httpd Not tainted 2.6.32.10 #2 Mar 24 19:22:28 alfa kernel: Call Trace: Mar 24 19:22:28 alfa kernel: [<ffffffff810c2ea3>] print_bad_pte+0x210/0x229 Mar 24 19:22:28 alfa kernel: [<ffffffff810c3c98>] unmap_vmas+0x44b/0x787 Mar 24 19:22:28 alfa kernel: [<ffffffff810c81d5>] exit_mmap+0xb0/0x133 Mar 24 19:22:28 alfa kernel: [<ffffffff81041f83>] mmput+0x48/0xb9 Mar 24 19:22:28 alfa kernel: [<ffffffff810463b0>] exit_mm+0x105/0x110 Mar 24 19:22:28 alfa kernel: [<ffffffff81371287>] ? tty_audit_exit+0x28/0x85 Mar 24 19:22:28 alfa kernel: [<ffffffff810477a0>] do_exit+0x1e9/0x6d2 Mar 24 19:22:28 alfa kernel: [<ffffffff81053c37>] ? __dequeue_signal+0xf1/0x127 Mar 24 19:22:28 alfa kernel: [<ffffffff81047d00>] do_group_exit+0x77/0xa1 Mar 24 19:22:28 alfa kernel: [<ffffffff810560f7>] get_signal_to_deliver+0x32c/0x37f Mar 24 19:22:28 alfa kernel: [<ffffffff8100a484>] do_notify_resume+0x90/0x740 Mar 24 19:22:28 alfa kernel: [<ffffffff8102724b>] ? __bad_area_nosemaphore+0x178/0x1a2 Mar 24 19:22:28 alfa kernel: [<ffffffff810272b9>] ? __bad_area+0x44/0x4d Mar 24 19:22:28 alfa kernel: [<ffffffff8100bba2>] retint_signal+0x46/0x84 Mar 24 19:22:28 alfa kernel: Disabling lock debugging due to kernel taint Mar 24 19:22:28 alfa kernel: swap_free: Bad swap file entry 6c800000 Mar 24 19:22:28 alfa kernel: BUG: Bad page map in process httpd pte:d900000000 pmd:1535b5067 Mar 24 19:22:28 alfa kernel: addr:00000037b400a000 vm_flags:08000875 anon_vma:(null) mapping:ffff88022b5d25a8 index:a Mar 24 19:22:28 alfa kernel: vma->vm_ops->fault: filemap_fault+0x0/0x34d Mar 24 19:22:28 alfa kernel: vma->vm_file->f_op->mmap: xfs_file_mmap+0x0/0x33 Mar 24 19:22:28 alfa kernel: Pid: 7512, comm: httpd Tainted: G B 2.6.32.10 #2 Mar 24 19:22:28 alfa kernel: Call Trace: Mar 24 19:22:28 alfa kernel: [<ffffffff81044551>] ? add_taint+0x32/0x3e Mar 24 19:22:28 alfa kernel: [<ffffffff810c2ea3>] print_bad_pte+0x210/0x229 Mar 24 19:22:28 alfa kernel: [<ffffffff810c3d47>] unmap_vmas+0x4fa/0x787 Mar 24 19:22:28 alfa kernel: [<ffffffff810c81d5>] exit_mmap+0xb0/0x133 Mar 24 19:22:28 alfa kernel: [<ffffffff81041f83>] mmput+0x48/0xb9 Mar 24 19:22:28 alfa kernel: [<ffffffff810463b0>] exit_mm+0x105/0x110 Mar 24 19:22:28 alfa kernel: [<ffffffff81371287>] ? tty_audit_exit+0x28/0x85 Mar 24 19:22:28 alfa kernel: [<ffffffff810477a0>] do_exit+0x1e9/0x6d2 Mar 24 19:22:28 alfa kernel: [<ffffffff81053c37>] ? __dequeue_signal+0xf1/0x127 Mar 24 19:22:28 alfa kernel: [<ffffffff81047d00>] do_group_exit+0x77/0xa1 Mar 24 19:22:28 alfa kernel: [<ffffffff810560f7>] get_signal_to_deliver+0x32c/0x37f Mar 24 19:22:28 alfa kernel: [<ffffffff8100a484>] do_notify_resume+0x90/0x740 Mar 24 19:22:28 alfa kernel: [<ffffffff8102724b>] ? __bad_area_nosemaphore+0x178/0x1a2 Mar 24 19:22:28 alfa kernel: [<ffffffff810272b9>] ? __bad_area+0x44/0x4d Mar 24 19:22:28 alfa kernel: [<ffffffff8100bba2>] retint_signal+0x46/0x84 Mar 24 19:22:28 alfa kernel: BUG: Bad page map in process httpd pte:2bfe8025 pmd:1535b5067 Mar 24 19:22:28 alfa kernel: page:ffffea0000f1f7c0 flags:4000000000000404 count:1 mapcount:-1 mapping:(null) index:0 Mar 24 19:22:28 alfa kernel: addr:00000037b400c000 vm_flags:08000875 anon_vma:(null) mapping:ffff88022b5d25a8 index:c Mar 24 19:22:28 alfa kernel: vma->vm_ops->fault: filemap_fault+0x0/0x34d Mar 24 19:22:28 alfa kernel: vma->vm_file->f_op->mmap: xfs_file_mmap+0x0/0x33 Mar 24 19:22:28 alfa kernel: Pid: 7512, comm: httpd Tainted: G B 2.6.32.10 #2 Mar 24 19:22:28 alfa kernel: Call Trace: Mar 24 19:22:28 alfa kernel: [<ffffffff81044551>] ? add_taint+0x32/0x3e Mar 24 19:22:28 alfa kernel: [<ffffffff810c2ea3>] print_bad_pte+0x210/0x229 Mar 24 19:22:28 alfa kernel: [<ffffffff810c3c98>] unmap_vmas+0x44b/0x787 Mar 24 19:22:28 alfa kernel: [<ffffffff810c81d5>] exit_mmap+0xb0/0x133 Mar 24 19:22:28 alfa kernel: [<ffffffff81041f83>] mmput+0x48/0xb9 Mar 24 19:22:28 alfa kernel: [<ffffffff810463b0>] exit_mm+0x105/0x110 ..... The entire log is here: http://download.netcenter.hu/bughunt/20100324/messages The actual kernel is 2.6.32.10, but the crash-series started @ 2.6.28.10. I have forwarded the tasks to another server, removed this from the room, and the hw survived memtest86 in >7 days continously + i have tested the HDDs one by one with badblocks -vvw, all is good. For me looks like this is not a hw problem. Somebody have any idea?
