Thanks for all the details, it’s very helpful!
I’ll get a few other set of eyes on this as this doesn’t trigger another “genius” idea here.
Could you just give me a couple more information that might be useful?
- MongoDB version ?
- Explain your cluster config (number of nodes, number of mongos, how many config servers, etc).
Anything suspicious in the logs of any of these nodes?
Thanks,
Maxime.
