SQL Server Alert System: ‘Severity Level 020: Error In Current Process – High’

I get this very vague Alert in a weekly basis and it was driving me nuts. I reached out to the IT Network/OS for months to see if they could pin down the issue and were not able to find anything on their logs. I provided an Event Handler Email Task to the developers to put inside their SSIS Packages and when I would get Severity Level 020 Alerts, I would now see their Packages. The common errors are

  • Named Pipes Provider: The specified network name is no longer available.

    A fatal error occurred while reading the input stream from the network. The session will be terminated

  • The prelogin packet used to open the connection is structurally invalid; the connection has been closed. Please contact the vendor of the client library. [CLIENT: <named pipe>]
  • Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library.
  • SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR.  The “OLE DB Destination.Inputs[OLE DB Destination Input]” failed because error code 0xC020907B occurred, and the error row disposition on “OLE DB Destination.Inputs[OLE DB Destination Input]” specifies failure on error.
  • Communication link failure

It did not matter when the Job ran (on a schedule, manual, Visual Studio Data Tools), it would still randomly fail. Most of these SSIS are straight forward where they pull 5 million records from Teradata to SQL– Just a straight SELECT * FROM Table (these tables are the final product of an ETL performed in Teradata). Then one day, I get a new error “Communication link failure” so I Googled it and here’s where it lead me to

I ran the command “Netsh int tcp show global” to see the following

In lamens term, Receive-Side Scaling is like the waiter directing traffic at a Food Buffet. The line can only move as fast as the waiter can find you a table. If you disable Receive-Side Scaling, it’s Free For All. You have eyes and the stranger next to you have eyes and you both can find an empty table without the help of the waiter therefore there’s no wait or less wait. Here’s a link to a more technical term

After I disabled Received-Side Scaling (Network Adapter -> Properties -Configure.. -> Advanced -> and increased the SQL (Properties -> Advance) Remote Login Timeout from 20 to 35,  the SSIS Packages began to run without Severity Level 020.

I hope this helps someone that is experiencing the same issue.

Modify Column Data Type

USE [YourDatabaseName]
ALTER COLUMN column_name datatype;

I have a database call Afterowl with a table call Birds. In my Birds table, I want to change TypeOfBird data type from NVARCHAR(10) to VARCHAR(100).

USE Afterowl

List Calendar Dates

I use this to bounce against my weekly ETL’s to make sure that every day of the week data is captured. This helps me quickly identify a Calendar date with no ETL date which means no data was pulled.

DECLARE @start_date DATETIME= ‘2017-01-01’;
WITH CalendarDates
AS (
SELECT CAST(@start_date AS DATE) AS Calendar_Day
SELECT DATEADD(DAY, 1, Calendar_Day)
FROM CalendarDates
WHERE Calendar_Day < @end_date)

SELECT Calendar_Day,
DATENAME(dw, Calendar_Day) AS Day_of_Week,
DATENAME(week, Calendar_Day) AS Week_Number


LIKE Regular Expression

Here’s a great trick to find specific patterns for a column. The LIKE CLAUSE can be use as a RegEx

Here’s a link to LIKE from Microsoft.

Using Wildcard Characters As Literals

You can use the wildcard pattern matching characters as literal characters. To use a wildcard character as a literal character, enclose the wildcard character in brackets. The following table shows several examples of using the LIKE keyword and the [ ] wildcard characters.

Symbol Meaning
LIKE ‘5[%]’ 5%
LIKE ‘[_]n’ _n
LIKE ‘[a-cdf]’ a, b, c, d, or f
LIKE ‘[-acdf]’ -, a, c, d, or f
LIKE ‘[ [ ]’ [
LIKE ‘]’ ]
LIKE ‘abc[_]d%’ abc_d and abc_de
LIKE ‘abc[def]’ abcd, abce, and abcf


In this example, I want to find all user names that starts with the letter “S” and is follow by numbers 0-9.
