Known issues in this update

Symptom  Workaround
If the PC uses an AMD Carrizo DDR4 processor, installing this update will block downloading and installing future Windows updates. This issue is resolved by KB4022726.
If a Server 2012 R2 system uses an Intel Xeon (E3 v6) family of processors, installing this update will block downloading and installing future Windows updates. This issue is resolved by KB4022726.
This security update introduced an issue in which, if an iSCSI target becomes unavailable, attempts to reconnect will cause a leak. Initiating a new connection to an available target will work as expected. Microsoft is working on a resolution and will provide an update in an upcoming release. For more information about this issue, see the following section.
More information about the iSCSI issue

Windows Server 2012 R2 and Server 2016 computers that experience disconnections to iSCSI attached targets may show many different symptoms. These include, but are not limited to:

  • The operating system stops responding
  • You receive Stop errors (Bugcheck errors) 0x80, 0x111, 0x1C8, 0xE2, 0x161, 0x00, 0xF4, 0xEF, 0xEA, 0x101, 0x133, or 0xDEADDEAD.
  • User log on failures occur together with a "No Logon Servers Available" error.
  • Application and service failures occur because of ephemeral port exhaustion.
  • An unusually high number of ephemeral ports are being used by the System process.
  • An unusually high number of threads are being used by the System process.

Cause

This issue is caused by a locking issue on Windows Server 2012 R2 and Windows Server 2016 RS1 computers, causing connectivity issues to the iSCSI targets. The issue can occur after installing any of the following updates:

Windows Server 2012 R2

Verification

  • Verify the version of the following MSISCSI driver on the system:

    c:\windows\system32\drivers\msiscsi.sys

    The version that will expose this behavior is 6.3.9600.18624 for Windows Server 2012 R2 and version 10.0.14393.1066 for Windows Server 2016.
  • The following events are logged in the System log:

    Event source

    ID

    Text

    iScsiPrt

    34

    A connection to the target was lost, but the Initiator successfully reconnected to the target. Dump data contains the target name.

    iScsiPrt

    39

    The Initiator sent a task management command to reset the target. The target name is given in the dump data.

    iScsiPrt

    9

    Target did not respond in time for a SCSI request. The CDB is given in the dump data.

  • Review the number of threads that are running under the System process, and compare this to a known working baseline.
  • Review the number of handles that are currently opened by the System process, and compare this to a known working baseline.
  • Review the number of ephemeral ports that are being used by the System process.
  • From an administrative Powershell, run the following command:

    Get-NetTCPConnection | Group-Object -Property State, OwningProcess | Sort Count

    Or, from an administrative CMD prompt, run the following NETSTAT command together with the "Q" switch. This shows "bound" ports that are no longer connected:

    NETSTAT –ANOQ

    Focus on ports that are owned by the SYSTEM process.

    For the three previous points, anything more than 12,000 should be considered suspect. If iSCSI targets are present in the computer, there is high probability that the issue will occur.

Resolution

If the event logs indicate that many reconnections are occurring, work with your iSCSI and network fabric vendor to help diagnose and correct the reason for the failure to maintain connections to iSCSI targets. Make sure that iSCSI targets can be accessed over the current network fabric. Install updated fixes when they become available. This article will be updated with the specific KB article number of the fix to install when it becomes available.

Note We do not recommend that you uninstall any of the March, April, May, or June security rollups. Doing so will expose the computers to known security exploits and other bugs that are mitigated by monthly updates. We recommend that you first work with iSCSI target and network vendors to resolve the connectivity issues that are triggering target reconnects.
