Database is in exclusive mode, connection request rejected

I keep seeing this error message in my logs on both a C-4 and C-7, appearing under 2.3.0.121 and 124.

org.quartz.JobPersistenceException: Failed to obtain DB connection from data source 'myDS': java.lang.IllegalStateException: Database is in exclusive mode, connection request rejected on line 604 (method parseUdp)

It appears against my Kasa devices that use the Community driver, but so far I can't pin anything down as to why the driver would be producing this outcome.

I have also tried restoring the database from yesterday morning's backup, but still the error appears in the log.

Any help would be appreciated....

It looks like you’ve overflowed the DB queue/buffer and it locked you out. @gopher.ny?

All good, I think I have solved the mystery, not a HE issue.
