description: Hi, Our openvz server crashed three times in a day with these errors. Is it something to with openvz kernel or can it be because of bad cpus (we have dual core dual amd opteron 270)? we use: 2.6.8-022stab078.10-enterprise Jul 9 12:19:41 vz01 kernel: CPU 0: Machine Check Exception: 0000000000000004 Jul 9 12:19:41 vz01 kernel: Bank 4: b604a00100000813 at 000000007e4f2f68 Jul 9 12:19:41 vz01 kernel: Kernel panic: CPU context corrupt Jul 9 05:44:28 vz01 kernel: CPU 0: Machine Check Exception: 0000000000000007 Jul 9 05:44:28 vz01 kernel: Unable to handle kernel paging request at virtual address 00f00094 Jul 9 05:44:28 vz01 kernel: printing eip: Jul 9 05:44:28 vz01 kernel: 023d7d02 Jul 9 05:44:28 vz01 kernel: *pde = 00000000 Jul 9 05:44:28 vz01 kernel: Oops: 0000 [#1] Jul 9 05:44:28 vz01 kernel: Bank 4: b404a00000000a13 at 0000000055c8df68 Jul 9 05:44:28 vz01 kernel: Kernel panic: Unable to continue Jul 9 05:44:28 vz01 kernel: SMP Jul 9 05:44:28 vz01 kernel: Modules linked in: simfs vzdquota af_packet ip_nat_ftp ip_conntrack_ftp iptable_nat ipt_state ipt_length ipt_ttl ipt_tcpmss ipt_$ Jul 9 05:44:28 vz01 kernel: CPU: 3, VCPU: 101:3 Jul 9 05:44:28 vz01 kernel: EIP: 0060:[<023d7d02>] Not tainted Jul 9 05:44:28 vz01 kernel: EFLAGS: 00010282 (2.6.8-022stab078.10-enterprise) Jul 9 05:44:30 vz01 kernel: EIP is at skb_drop_fraglist+0x22/0x50 Jul 9 05:44:30 vz01 kernel: eax: 57c8df60 ebx: 00f00000 ecx: 57c8df60 edx: 00f00000 Jul 9 05:44:30 vz01 kernel: esi: c0c0b0c0 edi: 0000003a ebp: 09724354 esp: 875cddc8 Jul 9 05:44:30 vz01 kernel: ds: 007b es: 007b ss: 0068 Jul 9 05:44:30 vz01 kernel: Process spamd (pid: 2662, veid=101, threadinfo=875cc000 task=b7170d40) Jul 9 05:44:31 vz01 kernel: Stack: 001b1b1f c0c0b0c0 023d7dea c0c0b0c0 c0c0b0c0 c0c0b0c0 023d7e20 c0c0b0c0 Jul 9 05:44:31 vz01 kernel: 0000003a 00000000 023d7ee1 c0c0b0c0 00000000 c0c0b0c0 0000003a 00000000 Jul 9 05:44:31 vz01 kernel: 02402e35 c0c0b0c0 00000000 875cdedc 0000003a 7690e600 c059f200 875cc000 Jul 9 05:44:31 vz01…

description: Thank you, Yes thats the same machine, I also compiled the kernel myself but got this error, DC also replaced all the RAM modules. Now they replaced them again, I think they will swap the CPUs next time.
