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:
