Additionally, some intrinsic problems within these modules may cause corruption of various memory structures that are necessary for the SQL Server process to function correctly. These modules might perform unsupported activities that include detouring important Win32 APIs and SQL Server routines, and calling risky APIs. This may be done to achieve a specific business logic requirement, an enhanced functionality, or intrusion monitoring.

These issues occur because applications or other software that are installed on a server that is running SQL Server can load certain modules into the SQL Server process (Sqlservr.exe). These issues occur because of the following causes for modules and filter drivers.

Memory dumps triggered for SQLDumper.exe may fail to complete hindering any troubleshooting activity.īecause of the nature of these issues, root cause identification often requires significant troubleshooting time and low level tracing.

Unexpected or unexplained failures when SQL Server processes make Windows API calls.

High CPU usage for the SQL Server process, especially privileged processor time.

100% CPU utilization and long database recovery times when you use In-Memory OLTP tables in SQL Server.

Exceptions (such as access violations), critical error messages about database consistency, assertion messages or unexpected process termination.

Slow response from SQL Server even if the concurrent amount of load or activity isn't unusually heavy.

Reports of various unresponsive-related error messages and conditions (SQL Server scheduler message such as 17883, application time-out messages, severe blocking within SQL Server).

In the scenarios, you may experience performance degradation and consistency issues of SQL Server Database Engine.
