I had a similar issue a few days back. Our engineering team concluded that this was a kernel bug. Not sure if there are any patches..but u can always log a call with RedHat and see what they say Regards, Ajay On 6/6/07, Shane Presley <shane.presley@xxxxxxxxx> wrote:
Hello, I had a RHEL4 system crash a day or two ago. First RedHat system that I've ever seen completely hung, requiring me to hard power cycle it. Felt like my Windows days. But then it happened yesterday as well. So something is wrong with this server. It's fully patched (up2date), and is a Dell 2850. I captured the /var/log/messages right before it panicked and here's the logs: Jun 4 21:26:42 myhost kernel: Unable to handle kernel paging request at virtual address 0f3514db Jun 4 21:26:42 myhost kernel: printing eip: Jun 4 21:26:42 myhost kernel: c01705b8 Jun 4 21:26:42 myhost kernel: *pde = 33c68001 Jun 4 21:26:42 myhost kernel: Oops: 0000 [#1] Jun 4 21:26:42 myhost kernel: SMP Jun 4 21:26:42 myhost kernel: Modules linked in: mptctl mptbase ipmi_devintf ipmi_si ipmi_msghandler dell_rbu autofs4 i2c_dev i2c_core sunrpc dm_mirror dm_mod button battery ac md5 ipv6 uhci_hcd ehci_hcd e1000 floppy ata_piix libata sg ext3 jbd megaraid_mbox megaraid_mm sd_mod scsi_mod Jun 4 21:26:42 myhost kernel: CPU: 0 Jun 4 21:26:42 myhost kernel: EIP: 0060:[<c01705b8>] Not tainted VLI Jun 4 21:26:42 myhost kernel: EFLAGS: 00010206 (2.6.9-55.ELsmp) Jun 4 21:26:42 myhost kernel: EIP is at __d_lookup+0x65/0x109 Jun 4 21:26:42 myhost kernel: eax: c2155c30 ebx: cada98f6 ecx: 00000011 edx: c212e200 Jun 4 21:26:42 myhost kernel: esi: 0f3514db edi: cada98f6 ebp: f43aa50c esp: f3789e0c Jun 4 21:26:42 myhost kernel: ds: 007b es: 007b ss: 0068 Jun 4 21:26:42 myhost kernel: Process bbtest-net (pid: 2942, threadinfo=f3789000 task=f24723b0) Jun 4 21:26:42 myhost kernel: Stack: 00000000 c2155c30 e1cbe00e cada98f6 0000000c f3789e80 cada98f6 00000000 Jun 4 21:26:42 myhost kernel: cada98f6 f3789f50 c0166ba3 f7f1be00 f3789e78 f3789e80 cada98f6 f543b548 Jun 4 21:26:42 myhost kernel: cada98f6 f3789f50 c0167475 00000000 00000000 00000000 fffcf000 c1c18aa0 Jun 4 21:26:42 myhost kernel: Call Trace: Jun 4 21:26:42 myhost kernel: [<c0166ba3>] do_lookup+0x23/0xb1 Jun 4 21:26:42 myhost kernel: [<c0167475>] __link_path_walk+0x844/0xc25 Jun 4 21:26:42 myhost kernel: [<c0167899>] link_path_walk+0x43/0xbe Jun 4 21:26:42 myhost kernel: [<c02d443f>] __cond_resched+0x14/0x39 Jun 4 21:26:42 myhost kernel: [<c01c3e8a>] direct_strncpy_from_user+0x3e/0x5d Jun 4 21:26:42 myhost kernel: [<c011b01b>] do_page_fault+0x1ae/0x5c6 Jun 4 21:26:42 myhost kernel: [<c0167c2e>] path_lookup+0x14b/0x17f Jun 4 21:26:42 myhost kernel: [<c0168309>] open_namei+0x99/0x579 Jun 4 21:26:42 myhost kernel: [<c015a599>] filp_open+0x45/0x70 Jun 4 21:26:42 myhost kernel: [<c02d443f>] __cond_resched+0x14/0x39 Jun 4 21:26:42 myhost kernel: [<c01c3e8a>] direct_strncpy_from_user+0x3e/0x5d Jun 4 21:26:42 myhost kernel: [<c015a8f5>] sys_open+0x31/0x7d Jun 4 21:26:42 myhost kernel: [<c02d5ee3>] syscall_call+0x7/0xb Jun 4 21:26:42 myhost kernel: Code: 24 0c 89 c2 81 f2 01 00 37 9e d3 ea 31 d0 8b 15 e8 a0 44 c0 23 05 e0 a0 44 c0 8d 04 82 89 44 24 04 8b 30 85 f6 0f 84 99 00 00 00 <8b> 06 0f 18 00 90 8d 5e 98 0f ae e8 8d 76 00 8b 44 24 0c 39 43 Jun 4 21:26:42 myhost kernel: <0>Fatal exception: panic in 5 seconds So I'm not sure what to make of that. I noticed one process name in there (bbtest-net) which is part of my BigBrother monitoring system. But that's been running OK for years, and hasn't been changed recently. Not sure where else to look. Could this be a hardware (memory?) problem? Shane -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
