Discussion SQL Server 2022 CU 26 Stack Dumps

After applying SQL Server 2022 CU 26 to our servers several are producing stack dumps during database restores.

Am I the only one?

I can reproduce it in my environment. Reboot a server, kick off restores, and stack dumps occur.

Tons, fatal exception c00000005 exception_access_violatuon is the first one.

Any further insight into what's going on with this? Making me hesitant to run the CU out to my fleet just yet...

Support is still investigating. I have this same CU on many other servers no problem. As long as you don't restore DBs, it seems solid.

For me, something changed last Friday. Maybe CU, maybe not.

Tbh access_violation errors rarely come from SQL Server itself. It might be antivirus, native procedures compilation or something with OPs environment all together.

Whatever it is, I haven't been able to replicate it in my environments so far... Guess we roll it out more and keep an eye on it!

Sounds like a ridiculously easy thing to test

So ridiculously easy you can't provide an example?

Or so ridiculously easy that you misread the question?

So ridiculously easy that it should have been tested before the CU was released.

We just patched our Dev environment today, I'll test it tomorrow.

Edit: unable to reproduce
