Training TEDLIUM3 on AWS GPU(TESLA ) instance with 480GB RAM and 64 CPU

It is hanging at

util/preprocess.py at line 69

out_data = pmap(step_fn, source_data.iterrows())

If I reduce the training filecount to 1000 files it will work. Please let me know what could be the reason and how can I resolve it.

please explain clearly @swamy sir

It was not a problem. Thank you. I thought is hanging because it taking over 30 minute on that step without any updates.
