After executing a single task inside a process the result is returned with state=finished raised error.

Error happens when trying to load a big dataset (over 5 GB). Otherwise the same dataset reduced to a smaller nrows executes and returns from result() without errors.

with concurrent.futures.ProcessPoolExecutor(max_workers = 1) as executor:
    results = executor.submit(pd.read_csv, path)

data = results.result()
