The lease between availability group 'HKERP_AlwaysOn' and the Windows Server Failover Cluster has expired.

The state of the local availability replica in availability group 'HKERP_AlwaysOn' has changed from 'PRIMARY_NORMAL' to 'RESOLVING_NORMAL'. The state changed because the lease between the local availability replica and Windows Server Failover Clustering (WSFC) has expired. For more information, see the SQL Server error log, Windows Server Failover Clustering (WSFC) management console, or WSFC log.

内存的page out导致sqlserver的网络超时进而导致sqlserver cluster超时。
因为在10:02时候有Mcafee对服务器的扫描，怀疑是mcafee的扫描导致的内存的page out。
进而导致了网络问题而引起sqlserver cluster的超时。

解决办法：
对sqlserver的服务器进行数据库的内存锁定。
