In this setup, assuming that you had an even distribution, you would
have around 223/4=55 records per hash slot and each slot should be

Can you attach with gdb to the process to see what is happening there?
Do you see any errors in the logs?

See the Overview in the documentation.
The expiry column is stores the binding's expiration time.

Do you see any errors in the logs?
Are you using FQDNs for registrar?
