Roman, test212 is specifically designed to exercise the queue code we've been discussing. It will cause the txn is waiting logs to show up.

Regression suite PRs #111 and #112 for 1.1 and 1.2 respectively.

Builds tested: Github 1.2.4-1 source

Reproduced the issue in 1.1.7-1 and the same error messages are still in 1.2.4-1 regression test.

Also, the first version is 1.2.4, but the PRs are for 1.1 and 1.2. Is the fix also in 1.1.8-1 regression?

I forgot to mention in my last comment that the regression test suite branch develop-1.2 was used for testing. In fact, I just tested it again using ColumnStore 1.2.4-1 RC and test212 still has the same error messages.

Build verified: Regression suite, develop-1.1 and develop-1.2
