[Jirka Ylönen]

OpenTripPlanner's GraphBuilder often stops to an error, when Overpass API returns

Is there something that one could do to this problem?

Hello,

This is not a standard usage pattern. We usually download OSM data and supply it as files to OTP. In fact, as far as I can tell RegionBasedOpenStreetMapProviderImpl is not even part of OTP anymore.

How are you triggering this module? Which documentation are you following?

My understanding is that the Overpass API is only intended for fetching small amounts of data and should not be used for such bulk downloads.
