You had OOM. For sure it isn’t related to that action you mentioned only.
hum, that’s curious. When you kill the instance and bring it back again in general it frees RAM. It should not go OOM again.
Do the following:
- Kill the instances and start again.
- Leave it for some time, 15 minutes maybe.
- Export your DB and upgrade.
We don’t have this version. Did you meant v20.07.0?
