This read-only counter tracks how many times the state machine, while still in the middle of authenticating, was interrupted by a reauthentication request and transitioned to ABORTING. An administrator monitors this to spot cases where periodic reauthentication timers are firing so frequently that sessions never get a clean chance to finish authenticating. For example, an unusually high count here might prompt the admin to check whether the configured reauthentication interval is set too short for this port.
