Jason Huynh commented on GEODE-597:
-----------------------------------
Have not been able to reproduce but looking at the logs it looked like two
different members thought they were coordinator. While one coordinator was
able to contact a third member, the other could not. The third member was then
booted from the system from the "fake" coordinator.
There have been quite a few changes in relation to membership and timing since
this failure. If it does not reproduce in a few more weeks, I will close the
ticket.
