The emfile in your errors indicates that you've run out of file descriptors.

See https://docs.couchdb.org/en/stable/maintenance/performance.html?highlight=handles#connection-limit for details.

You may also need to raise the file handle limit; see https://docs.couchdb.org/en/stable/maintenance/performance.html?highlight=handles#maximum-open-file-descriptors-ulimit for details on that.
