      Description

      On at least PMM 1.0.5 and greater the following error appears on MongoDB 3.2 clusters after 3.2.10 when using SCCC/mirrored config servers:

      2017-03-03T12:49:01.243+0000 W NETWORK [conn2036529] db exception when initializing on config, current connection state is { state: { conn: "SyncClusterConnection [config1:27019 (172.22.11.14),config2:27019 (172.22.11.15),config3:27019 (172.22.11.16)]", vinfo: "config:config1:27019,config2:27019,config3:27019", cursor: "(empty)", count: 0, done: false }, retryNext: false, init: false, finish: false, errored: false } :: caused by :: 6 all servers down/unreachable when querying: config1:27019,config2:27019,config3:27019
      

      This causes some queries in the mongodb_exporter to also fail. This is due to this MongoDB bug: https://jira.mongodb.org/browse/SERVER-27864

      A workaround to this issue has been created in percona/mongodb_exporter pull-request: https://github.com/percona/mongodb_exporter/pull/53.

      This ticket is to publicly track a fix for this problem.
