Description
The TestCompaction.TestRowSetCompactionSkipWithBudgetingConstraints scenario fails with the error like below when run on a machine with relatively high memory (it might be just a Docker instance with tiny actual memory allocated, but having the access to the /proc filesystem of the host machine). The full test log is attached.
