I'm seeing the same issue described in this old post, which unfortunately offers no further explanation or solution:
Re: Performance issues after upgrade
I'm running FusionAuth version 1.47.1 in a docker container.
The system seems to be behaving properly, but from time to time this error shows up in the logs:

Has there been a resolution for this?
