"STATUS_CONNECTION_RESET" error when an application reads a file in Windows Server 2012 R2 or Windows Server 2012

This article describes an issue that occurs on Windows Server 2012 R2-based or Windows Server 2012-based failover clusters. A hotfix is available to resolve this issue. The hotfix has a prerequisite.

Symptoms

Consider the following scenario:
  • You have two failover clusters that communicate across Ethernet gateways.
  • An application in the first cluster tries to read a file from the second cluster through Server Message Block (SMB) Multichannel.
  • There is continuous packet loss or connection disconnect issue between the endpoints due to too much network traffic.
In this scenario, the read request freezes on the node of the first cluster and any attempts to call the CancelSynchronousIO function also freezes. Additionally, you receive a "STATUS_CONNECTION_RESET" error message repeatedly until the computer crashes.

Cause

This issue occurs because SMB Redirector keeps retry indefinitely if the network disconnect error for Multichannel occurs until it hits the retry limit of 65,535, and then the computer crashes. SMB Redirector should eventually time out such request instead of retrying indefinitely.

Resolution

To resolve this issue, we have released a hotfix. Even though this issue has been observed only in Windows Server 2012 R2 or Windows Server 2012, the hotfix also applies to Windows 8.1, Windows RT 8.1, and Windows 8.

Important If you install a language pack after you install this hotfix, you must reinstall this hotfix. Therefore, we recommend that you install any language packs that you need before you install this hotfix. For more information, see Add language packs to Windows.
