3.1.5.1 Unused Registration Timer Event

If the server implements version 2 of the protocol, it MUST implement this timer event.

When the Unused Registration Timer (section 3.1.2.1) expires, the server MUST search for the WitnessRegistration entry in WitnessRegistrationList. If WitnessRegistration.IsAsyncNotifyRegistered is FALSE and WitnessRegistration.LastUseTime plus an implementation-specific time-out<7> is earlier than the current time, the server MUST remove the WitnessRegistration entry from the WitnessRegistrationList.
