DataSource.Error: ERROR [08S01] [Microsoft][Netezza] (1001) Communication link with server failed.

We face the exact same issue. Seemingly random, which of cource is frustrating. Some tables just does not work. They produce "ERROR [08S01] ... ". Also talked with our DBA's, they can't find any apparent differences between table that work and do not. Same database and schema. 

Obviously this is an old issue but the problem persists using the "2.97.861.0 64-bit (september 2021)" release of Power BI. 

Please note that the problematic tables work fine when using the generic ODBC connector toghether with an IBM supplied ODBC driver. This workaround works but also suggests that there should not be an issue with the built in driver.

I would appriciate if Microsoft points this out to Magnitude/Simba that assume supplies the built in ODBC driver. 

Thanks!
