Red Hat Bugzilla – Bug 1013014
Software NMI with abrtd
Last modified: 2017-12-06 07:55:36 EST
Description of problem:
We were tracing a segfault within a third party package. But abrtd rejected the coredump with the message: Package 'php53u-fpm' isn't signed with proper key
So we added the signing key filename to /etc/abrt/gpg_keys and restarted abrtd afterwards. This worked well for a couple of minutes, so the application crashed and abrtd accepted the package. We now have some coredumps and aleady filed a bug for that.
After one of the crashes the server suddenly rebooted with the following Message on the Servers Lights Out Interface:
09/27/2013; 14:40:59 0x816f08132582ffff System "SN# KD66BKR" has recovered from an Uncorrectable Bus Error
09/27/2013; 14:40:36 0x816f03131701ffff System "SN# KD66BKR" has recovered from an NMI
09/27/2013; 14:40:25 0x806f08132582ffff A Uncorrectable Bus Error has occurred on system "SN# KD66BKR"
09/27/2013; 14:39:16 0x806f03131701ffff A software NMI has occurred on system "SN# KD66BKR"
The Server is a IBM System X 3650 M3 and we have seen this issue on two different Machines.
The /var/log/messages now contains no entries about that and we can't find any evidence for start of the crashkernel. Fortunately i had a less on /var/log/messages:
