"Unknown connection problem to zenhub" messages in zenhub log

    We are running Zenoss 6.2.1 (Community). Recently we started getting a lot of these messages in the zenhub service log:

    CRITICAL zen.pbclientfactory: Unknown connection problem to zenhub <class 'twisted.spread.pb.PBConnectionLost'>

    We are getting 2-3K such messages a day. This started a few days ago. We recently made some configuration changes to resolve some performance issues:

    1. Increased zenhub instances: 1 -> 2
    2. Increased zenhub workers. Currently at 26.

    I know that the number of zenhub workers is WAY too high, but we're trying to resolve problems with missed runs and discarded events.

    Any ideas on how to resolve this error message?

    We are also seeing a lot of this message:

    INFO zen.ZenHub: Worker 11 (5394) reports 2020-05-22 04:09:28,693 INFO zen.pbclientfactory: Initial connect timed out after 30 seconds

    Thanks in advance,
