------------------------------------

             Summary: Unattributable error on nifi shutdown when controller service was unable to be started
                 Key: NIFI-10772
                 URL: https://issues.apache.org/jira/browse/NIFI-10772
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.18.0
            Reporter: Nissim Shiman


This error occurs when nifi is unable to start an controller service that is supposed to be in an enabled state.

For example, if the StandardSSLContextService is running, but the underlying keystore file it relies on is removed from the filesystem, nifi will be unable to successfully start it on a nifi restart.

When nifi is shutdown the following error is in nifi-app.log:
{code}

It is unclear from the current log output as to what the underlying cause of it was (i.e. which controller service StandardControllerServiceNode is having trouble with)
