The AppFabric Cache in our production crashes almost every day, and is highly unstable. The below errors are logged:

Microsoft.ApplicationServer.Caching.DataCacheException: ErrorCode:SubStatus:There is a temporary failure. Please retry later. (Sufficient secondaries not present or they are in throttled state.)

Microsoft.ApplicationServer.Caching.DataCacheException: ErrorCode:SubStatus:There is a temporary failure. Please retry later. (The request did not find the primary.)

AppFabric Caching service crashed.{Lease with external store expired: Microsoft.Fabric.Federation.ExternalRingStateStoreException: Lease already expired at Microsoft.Fabric.Data.ExternalStoreAuthority.UpdateNode(NodeInfo nodeInfo, TimeSpan timeout) at Microsoft.Fabric.Federation.SiteNode.PerformExternalRingStateStoreOperations(Boolean& canFormRing, Boolean isInsert, Boolean isJoining)}

Could someone please provide me some inputs? This is a HA enabled cache environment with 3 cache hosts. All of them are running on Windows Server 2008 Enterprise Edition, and the SQL Server is used for config.
