Mapbox studio Classic (v 0.3.4) hanged when exporting to .mbtiles

[nouryf]

Hi,

I downloaded a country osm.pbf and converted it to postGIS using the steps outlined here:
https://github.com/kartotherian/kartotherian/blob/master/README.md#in-depth-step-by-step

Then I cloned the 'osm-bright.tm2source' https://github.com/kartotherian/osm-bright.tm2source

I opened my dataset fine using MapBox studio classic and verified that data are displayed on/off based on zoom levels as expected per the dataset tm2 definition.

I saved my project, then clicked 'Export to MBTiles' to produce vector tiles. The progress displayed initially 0.1 % but kept increasing over time (36 h) until it reached 63.1 %. At that level it got stuck for 6 hours without any incremental change. I looked at my CPU usage and it was near 0%. So the tile production seems to either hang or stopped. When the tile generation was ongoing my CPU was showing 100% usage (mostly node.exe installed with MapBox Studio Classic).

After 6 hours of no progress beyond 63.1% and no CPU action, I 'canceled' the export.

I wonder what could hang or stopped the process ? Any hint where to look ? as no error was displayed.

Thanks
