SQL Server: EXCEPTION_ACCESS_VIOLATION when Updating Statistics

ISSUE:
Hello everyone, I got an incident when running update statistic on SCCM database.
the UpdateStat was generating lots of dump file with the error bellow:

***Stack Dump being sent to I:\MSSQL10_50.MSSQLSERVER\MSSQL\LOG\SQLDump0048.txt
SqlDumpExceptionHandler: Process 55 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
* *******************************************************************************
*
* BEGIN STACK DUMP:
*   02/29/16 14:38:56 spid 55
*
*
*   Exception Address = 000007FEF15DB985 Module(sqllang+000000000068B985)
*   Exception Code    = c0000005 EXCEPTION_ACCESS_VIOLATION
*   Access Violation occurred reading address 0000000000000000
* Input Buffer 50 bytes –
*             sp_updatestats

CAUSE:
The issue was caused because database is configured to automatically update statistics and one statistic got corrupted.

RESOLUTION:
– Run sp_updatestats again and check in which table the error is ocurring.

Updating [dbo].[PullDPResponse]

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

– Now we know statistics on [dbo].[PullDPResponse] is corrupted. Lets check stats individually to identify which one is corrupted. That table has two:

DBCC SHOW_STATISTICS(‘PullDPResponse’,’PullDPResponse_PK’);   <– It works
DBCC SHOW_STATISTICS(‘PullDPResponse’,’_WA_Sys_08000002_59A78896′)   <– Not working

– Lets drop corrupted stats:

DROP STATISTICS PullDPResponse._WA_Sys_08000002_59A78896;

– Now we are good need to update all stats to make sure everything is fine.

TNSPING Message 3511 not found; No message file for product=NETWORK, facility=TNSMessage 3512 not found;

I got this error when try to run TNSping after install Oracle client (x86 and x64) on Windows Server 2012 R2:

C:\Users\admlucas_almeida>tnsping
TNS Ping Utility for 64-bit Windows: Version 11.2.0.1.0 – Production on 13-OCT-2015 07:47:32
Copyright (c) 1997, 2010, Oracle.  All rights reserved.

Message 3511 not found;
No message file for product=NETWORK, facility=TNSMessage 3512 not found;
No message file for product=NETWORK, facility=TNSMessage 3513 not found;
No message file for product=NETWORK, facility=TNSMessage 3509 not found;
No message file for product=NETWORK, facility=TNS

It´s just a oracle client installation, ORACLE_HOME is set correctly.

RESOLUTION:

nlus.msb did exist under %ORACLE_HOME%\network\mesg\, but there were seven more msg files missing. Apparently this was due to an incomplete client installation, and I had copied these file across from another machine with the same version/configuration and got rid of the issue.
