Returns the maximum number of lease updates which can be held unsent in the communication-recovery state.
If the server is in the communication-recovery state it is unable to send lease updates to the partner. Instead it keeps lease updates, hoping to send them when the communication is resumed. This value designates a limit of how many such updates can be held. If this number is exceeded the server continues to respond to the clients but will have to go through regular lease database synchronization when the communication is resumed.

Returns a maximum number of clients for whom lease updates failed due to other than general error.
A lease update may fail due to a conflict with the partner's configuration. The server distinguishes such errors from general errors (e.g., related to communication issues) to avoid transitioning to the partner-down state when there is in fact a problem with a lease or the configuration. On the other hand, if such problematic leases accumulate, the server can no longer provide the HA service and should transition to the terminated state. Consequently, an administrator must fix the configuration problem. This function returns the maximum number of clients with conflicting leases before the server transitions to the terminated state.
