SQL Server 2022 CU18 Crashing with EXCEPTION_ACCESS_VIOLATION

Anonymous

SQL Server 2022 CU18 is experiencing crashes approximately 1-2 times a month since installation. The error log shows the following message:

2025-03-18 08:20:04.77 spid70 SqlDumpExceptionHandler: Process 70 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.

The stack dump details include:

It looks like the error log is from a Deltek Product. The fix is to use trace flag 11042 from CU documentation https://learn.microsoft.com/en-us/troubleshoot/sql/releases/sqlserver-2022/cumulativeupdate22 see Incorrect behavior of SESSION_CONTEXT in parallel plans section

I would recommend that you open a support case. Crashes like this are often token of bugs in SQL Server. Although, you may want to check if you are using of these:

Extended stored procedures.
Unsafe assemblies.
sp_OAxxxxx.
Linked servers to non-Microsoft data sources that run in-process.

These are components that could scribble the memory and pull the rug for SQL Server.

It is very difficult to analyse these stack dumps without access to the source code, hence my suggestion to open a support case.

Thanks Erland for the suggestion. I have a hard time trying to find a way to open a support case. It keeps asking for a support plan (contract or subscription) but offer no way to purchase one.

I would call your local Microsoft subsidiary. Well, if you are in a larger organisation, I would talk to your IT department, who probably already have a support contacts within Microsoft.

I will need to confess that I like to think that if you can afford the license for Enterprise Edition, you can also afford a support contract. But how you buy them? I've never had a role where I have needed to know that.

I reached out to our Microsoft reseller and got the information I needed for the support. Thanks! Got this part figured out.

Hi !

I was wondering if you had any come back from Microsoft regarding this?

Also, just to make sure you're saying it happens 1-2 times a month but CU18 was released on March 13th. Is there something I am missing?

Thank you
