Missing new document right after 'No DB shards could be opened' error

[uvizhe]

Description

I've posted a new doc to my DB but it's missing somehow. POST request returned Ok.
Looking at logs I see an error message right before my POST.

Steps to Reproduce

IDK

Expected Behaviour

I would either expect to see a posted document in a DB or a failed POST request.

Your Environment

I'm running CouchDB in a Docker container on a local PC.
My CouchDB has 3 databases with less than a hundred docs overall.

• CouchDB version used: v. 3.0.0 (https://github.com/apache/couchdb-docker)
• Operating system and version: Ubuntu 16.04.4 LTS

Additional Context

As per config:

[couchdb]
max_dbs_open = 500
[cluster]
q=2
n=3

Here is two consecutive log messages:

Hi there,

This is not a CouchDB bug. GitHub is for actual CouchDB bugs only. We're quite sure the Docker container works due to exhaustive testing. Most likely, you have misconfigured the node name vs. the data stored for the databases you're trying to access. Your POST request returned 500, not 200, so it very much was not an OK.
