On Tuesday August 14 we published a Security Update for six different releases of SQL Server 2016 and 2017. For one of those releases, SQL Server 2016 SP1 GDR (KB4293801), an issue may occur after applying the update where the sqlceip.exe process experiences an unhandled exception. This will only occur if the updated instance was currently configured to collect SQL Customer Experience Improvement Program (CEIP) information. This does not impact the operation of the updated SQL Server engine, however this may impact a SQL Server Failover Cluster Instance node if configured for CEIP.
Please note that this issue only impacts the SQL Server 2016 SP1 GDR (KB4293801) release, which is for SQL Server 2016 SP1 instances that have not had any CU updates applied.
