I don't see any existing bug for the same crash for Splunk 6.1 or specifically 6.1.6 which is what I believe you have. I'd confirm, based on what I am seeing, that you have THP disabled. It is a memory management scheme that can cause problems when left enabled on instances running Splunk. This can include a variety of memory and stability issues and crashes:

If that is already disabled, I would upgrade to the latest version of 6.1 which is 6.1.13, to eliminate any potential bugs you may be encountering.

We are on v6.5.2 and are also observing this error. I can confirm that we have THP disabled.
