We have a MongoDB community edition ver 4.4 as ReplicaSet (3 nodes).
We are using Docker tag: mongo:4.4.10
All 3 containers abruptly restarts themselves. This happened twice in the last 2 days.
I have scoured all metrics (Datadog integration) and logs, but can’t place anything at all.
When this happens the containers restart themselves 2-3 times before the cluster reforms.
It is not OOM, I’ve check system logs.
Any pointers to what else I can check will be helpful. I am not very operation savvy about MongoDB itself, so may have missed something. So don’t leave our obvious suggestions too.
TIA.
