Description

This happened during a failover test so it's likely that there were non-nominal things occurring such as connections being terminated abruptly.

I looked at the release notes for 3.6.0 and 3.7.0 and I don't see a fix for this issue.

Program terminated with signal 11, Segmentation fault.
