Four days ago I upgraded (with apt-get) from 2.0.1. to 2.1.0 my single node elastic search on ubuntu in aws. After the upgrade system continuously die after minutes without any message in the logs. After several probes, I tried it in a new fresh 2.1.0 host, without any results: system crash again!
After I saw that the snapshot/restore are not compatible from 2.1.0 to 2.0.1 I done a full reindex of data in a fresh 2.0.1 ES and now is stable again.
Did you have any suggestion?
Thank you in advance, marco
