Trying to debug a database server getting cpu softlocks causing SSHD to hang and not let anybody log in. Figured that a good first step would be to get some kernel dumps when the problem occurs. According to what I read at the following web site, I can get dumps for softlock problems too. Here's the site: http://blog.kreyolys.com/2011/03/17/no-panic-its-just-a-kernel-panic/ Using a throwaway 32 bit dev server, I followed the directions exactly with the below modifications. A) I got the kernel-debuginfo and kernel-debuginfo-common by enabling /etc/yum.repos.d/CentOS-Debuginfo.repo and then installing with yum. B) One other change is that I had to use an alternate partition instead of the one resolving "/var" because the server was set up with LVM. The partition that I used ("/dev/sdb3") is actually mounted at /alt/home. So when I simulate a crash by piping a "c" to /proc/sysrq-trigger, I see the following in /var/log/messages: May 30 13:37:24 norman kernel: SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) thaw-filesystems(J) saK show-backtrace-all-active-cpus(L) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W) dump-ftrace-buffer(Z) But nothing else. NO files in /var/crash, or /alt/home/var/crash (directory exists) Nothing happens at all when I run # echo 1 > /proc/sys/kernel/softlockup_panic I've tried tweaking a few settings in /etc/kdump.conf, restarting after each time (since it creates a new boot img) to no avail. What am I messing? Here's a bunch of hopefully relevant info: kernel line in grub.conf: kernel /vmlinuz-2.6.32-358.6.2.el6.i686 ro root=/dev/mapper/VolGroup-lv_root nomodeset rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD rd_LVM_LV=VolGroup/lv_swap SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto quiet rd_LVM_LV=VolGroup/lv_root KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM crashkernel=128M nmi_watchdog=1 # grep -v "#" /etc/kdump.conf ext4 /dev/sdb3 path /var/crash core_collector makedumpfile -c -d 31 # cat /proc/meminfo MemTotal: 379352 kB MemFree: 232748 kB Buffers: 22496 kB Cached: 79040 kB SwapCached: 0 kB Active: 60512 kB Inactive: 60152 kB Active(anon): 20028 kB Inactive(anon): 4640 kB Active(file): 40484 kB Inactive(file): 55512 kB Unevictable: 0 kB Mlocked: 0 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 379352 kB LowFree: 232748 kB SwapTotal: 1048568 kB SwapFree: 1048568 kB Dirty: 48 kB Writeback: 0 kB AnonPages: 19124 kB Mapped: 14320 kB Shmem: 5556 kB Slab: 16216 kB SReclaimable: 8444 kB SUnreclaim: 7772 kB KernelStack: 816 kB PageTables: 2188 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 1238244 kB Committed_AS: 164964 kB VmallocTotal: 506396 kB VmallocUsed: 5344 kB VmallocChunk: 491856 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 9692 kB DirectMap2M: 514048 kB // IN sysctl.conf kernel.unknown_nmi_panic=1 kernel.panic_on_unrecovered_nmi=1 vm.panic_on_oom=1 kernel.sysrq = 1 # /cat/proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 1 model name : Intel(R) Pentium(R) 4 CPU 1.50GHz stepping : 2 cpu MHz : 1495.192 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm up pebs bts bogomips : 2990.38 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 32 bits virtual power management: # dmesg: Initializing cgroup subsys cpuset Initializing cgroup subsys cpu Linux version 2.6.32-358.6.2.el6.i686 (mockbuild at c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Thu May 16 18:12:13 UTC 2013 KERNEL supported cpus: Intel GenuineIntel AMD AuthenticAMD NSC Geode by NSC Cyrix CyrixInstead Centaur CentaurHauls Transmeta GenuineTMx86 Transmeta TransmetaCPU UMC UMC UMC UMC BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000001ff77000 (usable) BIOS-e820: 000000001ff77000 - 000000001ff79000 (ACPI NVS) BIOS-e820: 000000001ff79000 - 0000000020000000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee10000 (reserved) BIOS-e820: 00000000ffb00000 - 0000000100000000 (reserved) DMI 2.3 present.
