FIX: Unexpected memory consumption when TCP protocol connections are used for SQL Server 2017 on Linux

Applies to: SQL Server 2017 Developer LinuxSQL Server 2017 Enterprise Core on LinuxSQL Server 2017 Enterprise on Linux


Assume that you use SQL Server 2017 on Linux. When you connect to SQL Server by using the TCP/IP protocol, a handle leak might occur. Over time, this leak can exhaust the handle table or memory, leading to varied and unexpected behavior, such as out-of-memory errors, unable to open new connections, and so on.


This fix is included in Cumulative Update 4 for SQL Server 2017.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
