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

Error Message:
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. [CLIENT: 100.100.100.200]

Root Cause:
1) If you open telnet session and type some characters then sql server will start processing those bytes which are actually junk and will give this error.
2) Some application is mistakenly sending information to the port in which SQL Server is listening which becomes junk information to SQL Server.
3) Client Driver which generated the TD Packets is having problem is preparing proper Packets.

Solution:
Find out the client from the IP Address and fix the issue in driver.
