Comment 0 for bug 1828534

Designate has to use Worker and Producer as of Rocky as the support for zone manager and pool manager was up for removal in Rocky. This was addressed in https://bugs.launchpad.net/charm-designate/+bug/1773190

During a Queens to Rocky upgrade I ran into an issue with designate-producer being down (see the details below).

I was able to successfully start designate-producer by hand. It looks like there were several attempts to restart the service by systemd itself ("Scheduled restart job, restart counter is at 5.") which eventually failed when the failcount became higher than 5. Debugging mode was disabled so I did not see anything in the producer log.
