SQL Server service stops unexpectedly – Microsoft SQL Server Standard (64-bit) v15.0.4445.1

Hello,

I’m experiencing an issue with Microsoft SQL Server Standard (64-bit), version 15.0.4445.1. The SQL Server service crashes at least once per day, and sometimes even more frequently. When this happens, users lose access to the databases hosted on the server until I manually restart the service.

I have attached the event logs where the related error entries can be seen, which I believe will help you identify the cause of the issue.

Could you please help me determine the root cause of the service failure and how to prevent it from happening again

    Often crashes like this are tokens of dump in SQL Server, but it can also be due to things running locally. This includes:

    • Home-written or third-party extended stored procedures.
    • Use of the sp_OAxxxx procedures to run COM objects.
    • Linked servers using third-party or home-written OLE DB/ODBC drivers that run in-process.
    • Unsafe CLR assemblies.

    They are all things that could clobber SQL Server memory or their own run into crashes.

    And looking at your stack dump, I get the impression that the crash indeed occurs during a call to the CLR. So you should invest what CLR you are running on the server.
