KB2884953 - FIX: "Non-yielding Resource Monitor" when you run a workload that executes concurrent queries in SQL Server 2012

Symptoms

Assume that you have some tables that contain clustered columnstore indexes in a Microsoft SQL Server 2012 instance. When you run a workload that executes concurrent queries against the tables, the following error messages about the Resource Monitor task are logged in the SQL Server error log:

<Date><Time> Server      Using 'dbghelp.dll' version '4.0.5'
<Date><Time> Server      **Dump thread - spid = 0, EC = 0x0000000000000000
<Date><Time> Server      ***Stack Dump being sent to C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\LOG\SQLDump0860.txt
<Date><Time> Server      * *******************************************************************************
<Date><Time> Server      *
<Date><Time> Server      * BEGIN STACK DUMP:
<Date><Time> Server      *   <Date><Time> spid #
<Date><Time> Server      *
<Date><Time> Server      * Non-yielding Resource Monitor
<Date><Time> Server      *
<Date><Time> Server      * *******************************************************************************
<Date><Time> Server      * -------------------------------------------------------------------------------
<Date><Time> Server      * Short Stack Dump
<Date><Time> Server      Stack Signature for the dump is 0x00000000000002FF
<Date><Time> Server      External dump process return code 0x20000001.
External dump process returned no errors.


Additionally, you may encounter 100 percent CPU utilization, and the instance of SQL Server freezes. You have to restart SQL Server to resume operations. As a side effect, you may also notice a "Non-yielding Scheduler" message after the "Non-yielding Resource Monitor" message.
