Steps to Reproduce

There is no specific use case to replicate this behavior.

Root Cause

A configuration issue in the operating environment is responsible for this issue. The database backup configuration was changed, causing the overnight database backup operation to not be completed by the time peak usage hours began.

Resolution

Stop the backup operation.
Revert the database configuration to its previously known working form before the next backup is taken, to address the issue in the long term.
