GTFS of the Netherlands: unexpected exception and transit feed validator crash

[glagolight]

Hello,

I have tried to analyze the following GTFS:

Source : https://navitia.opendatasoft.com/explore/dataset/nl/table/?sort=3D=type_file
Nr. 2 in the list: Global Transport in Netherlands
Download : 2017 08 31
Data Date : 2017 08 30
Data valid until : 2017 11 28

and

Source 2 : https://transitfeeds.com/p/ov/814
Download : 2017 08 31
Data Date : 2017 08 29
Data valid until : unknown

In both cases, I have met an unexpected exception with the GTFS Validator.

Please find the error message in attachment (.TXT files).

Feel free to contact me for any question or precision.
Thank you in advance for your help,
Kind Regards,
Glagolight

It looks like the feeds are too large for the memory of the machine you tried to run this on.
