Support says this is known issue (SPL-153976) and fixed as part of 7.1.3 (https://docs.splunk.com/Documentation/Splunk/7.1.3/ReleaseNotes/Fixedissues), I am upgrading tonight to check if it works.

Engager

Same thing on 7.1.2 on CentOS Linux release 7.5.1804 (Core), all 3 nodes of a Search Head Cluster crashed almost simultaneously!

Yeah I am still dealing with this issue. Did you figure out your issue?

Same here, one or more searchheads crash several times a day, After recent upgrade to splunk 7.2. Support Call is already in progress. No solution so far. As a workaround we just restart them.

7.1.4 is out, it might be worth a try...

Support recommended me to update to 7.1.3.

@scc00 -- Please submit a Support Case for this issue as we have recently had several reports very similar to this one. This is something that our Developers will need to look into.

My first thought on this issue as its a SIG-11 SegFault is that the System ran out of available Memory (RAM) and the Kernel Killed off this Search Process to prevent a Kernel Panic. You may be able to overcome this issue if it is Kernel Related by updating the Linux Kernel in use on that AWS Linux AMI. If possible as a Linux Administrator what I would do is setup a CentOS instance to see if this issue is present with that Linux Distro.

From the "Crash Report" provided I can see that the Splunk process that was "killed" was a Search. This was seen from the following line of the Printout you provided:

[0x0000556D51DB0820] ZN16SearchResultsMem23appendSharedDestructiveERS + 208 (splunkd + 0x1029820)

This is showing that a Search appears to have attempted to update its Memory Location with some new data and could not complete that process. We will need to have you submit a Support Case to have this issue reviewed by the Splunk Developers.

Thank you,

So I found an error within /var/log/messages that mirrored the time of the crash. It seems NTP was out of sync and kept terminating on the OS. So i removed NTP and switched over to AWS chrony and so far so good. I will update this thread in a few days when I am certain this was the resolution.

@scc00 -- Thank you for that information and that sounds like a Really BAD Bug on the AWS Linux AMI side of things if NTP is not viable for use. I would reach out to AWS as NTP is a Default Linux Tool for Syncing Time and should be able to be used in the AWS Linux AMI without causing a SIG-11 SegFault in an application that requires Time to be Synced between instances.

The fact that you had to remove NTP and change to using Chrony would suggest that AWS may have introduced a Bug into their Kernel that prevents NTP from running and forcing their users to use the "In-House" AWS Time Sync Services. This should be "Good-2-Go" for use but if there is ever a Time Sync issue at AWS then this type of issue could return.

It might be worth testing another Linux Distro for your Environment such as CentOS, Ubuntu, RHEL (RedHat), or SuSE Linux. I do know that these Linux Distros work with NTP "Out-of-the-Box" at AWS.

Again thank you for that info, I will add it to my "Potential Causes" Bag of tricks.

So the new test box crashed twice after fixing the NTP error. Now it's crashing with the below error in /var/log/messages/

So Splunk told me to adjust the CPU and clean up some skipped searches and limits.conf. Implemented all of that but now the instance still crashes but now i'm seeing the CPU spiking caused by search and scripted input. Then the instance crashes again with the same error above.
