  This issue occurs when a TCP connection breaks and then reconnects. A TCP acknowledgement is not received in the node-to-node communication on a Windows Server 2012 R2 failover cluster, and the node that does not receive the TCP acknowledgement is removed from the active failover cluster membership. Error 5023 is logged in the cluster.log file of the node that is removed from the active failover cluster membership. For example, the following error 5023 is logged in the cluster.log file on the   FC-NODE2 node that corresponds to the previous System log:
00000b7c.00001254::Date-Time WARN [PULLER FC-NODE2] ReadObject failed with GracefulClose(1226)' because of 'channel to remote endpoint fe80::####:####:####:####%##:~49256~ is closed'.

  When you delete network interfaces on a server that is running Windows Server 2012   R2 or Windows Server 2012, you experience random and intermittent crashes on the system, and you also receive one of the following Stop error messages:
  •0xD1: DRIVER_IRQL_NOT_LESS_OR_EQUAL
  •0X139: KERNEL_SECURITY_CHECK_FAILURE
  •0x3B: SYSTEM_SERVICE_EXCEPTION

  Assume that a disk resource name contains unauthorized file system characters, such as colon (:) or backslash (\), in a Windows Server 2012 R2 or Windows Server 2008 R2-based failover cluster, and the disk becomes dirty. In this situation, the chkdsk command does not run as expected, and the disk resource cannot come online.

Issue 1
Consider the following scenario:
•You connect a VM to a virtual switch that uses a physical adapter.
•You enable the single root I/O virtualization (SR-IOV) option in Virtual Switch Manager.
•You disable the physical adapter on the Hyper-V guest while network I/O is running in the VM.
In this scenario, the VM crashes.
Issue 2
The current Write Ahead Logging (WAL) implementation incorrectly assumes that the Virtual Hard Disk (VHD) ownership never changes. However, the ownership does change in multiple VM group replication in a shared VHD scenario
