|
_time=2020-06-09T09:18:10.161-07:00 _level=INFO _msg=New store created with url http://[::1]:8091
|
_time=2020-06-09T09:18:10.161-07:00 _level=INFO _msg=pollEOF: About to start stdin polling

A similar query crash was also seen with the same steps in 7.0.0-2017 & 7.0.0-2208, but only once. Here in 7.0.0-2278, we see this happening 12 times. Not sure if something has regressed since 7.0.0-2017 or 7.0.0-2208.
