DFSR service crashes or freezes randomly during data replication in Windows Server 2012 R2

Symptoms

Problem 1

When the DFSR service crashes, Distributed File System Replication (DFSR) replication is stopped, and event ID 1000 is logged in the event log. The log entry resembles the following:

Log Name: Application
Source: Application Error
Date: Date
Event ID: 1000
Task Category: (100)
Level: Error
Keywords: Classic
User: N/A
Computer: Computername
Description:

Faulting application name: DFSRs.exe
Faulting application path: C:\Windows\system32\DFSRs.exe
Exception code: Access violation - code c0000005

dfsrs.exe version 6.3.9600.17396

Problem 2

If you installed May 2016 update rollup 3156418 on Windows Server 2012 R2, the DFSRS.exe process may consume a high percentage of CPU processing power (up to 100 percent). This may cause the DFSR service to become unresponsive to the point at which the service cannot be stopped. When this problem occurs, you must hard-boot affected computers to restart them.
