Hello dear forum,

Today I have installed the new version of SA (17.0.6.2757 SP 1), and I found out that it is possible to crash dbsrv17.exe (64-bit) with the SQL Profiler, if you choose the option as you see in the image below:

To reproduce this, please follow steps:

  1. Start the profiler;
  2. Choose "Targeted";
  3. Click "Insert Criteria" and choose "sql_string";
  4. Remove the number 10 (seconds) in the text box above;
  5. Press OK
  6. Start dbsrv17, because it should crash :(

My purpose was to trace all SQL statements that have the specific table name (I was trying to capture what the application is doing with the DB). I have already submitted two crash reports, but I'd like to hear from you, whether you have the same behavior.

p.s. maybe this isn't a bug, but a feature.

Thanks,
Vlad

Ah yes, something to add to the list of reproducible actions to crash the database server, as created by Reimer:

How to crash a SA11 engine with a simple SQL statement

(although here it's no simple SQL statement, apparently...)

And a nice way to introduce 17.0.6 - I wasn't aware of that:)

(Studying the readme it seems that one has not the same number of new features as 17.0.4...)

I forgot to mention, even with an empty DB, one can crash the process. Do you have a chance to check my steps?

Sorry, not currently... - I have not yet installed the EBF:(

This definitely is bug, not a "feature". We'll look into it.

Thank you, Chris. If you will update the thread with the results, it will be super!
I want to know whether you are able to reproduce it as well.

I was able to reproduce it. Your instructions were very clear and easy to follow.
