APD based on Query fails randomly when using parallelization


We are using an APD to write data from a Query to a CSV file. After this ran way too long, we set up a parallelization group (RZ12) and use that group in the APD.

We have set the package size for a partitioning characteristic (a date) to value 5.

For some reason the APD failes with error message "Error during parallelization: Assignment error: Overwriting of a protected field" (RSAN_RT352).

This happens about half of the times we run the APD. I haven't found anything regarding this error.

Any ideas?

    you have enough processes available for this apd?

    are you launching manually or via process chain?

    • There should be enough processes available. It is started via process chain, but the error has also occurred when starting it manually and there was not happening much in the system at the same time.
