I have launched an upload of 3000 images using the GWToolset − actually two, one yesterday night with the first 1200 files, another one this morning with the 3K files minus the 100 uploaded in the night

Here are the logs :

(batches are dated in the summary)

Two things:
* uploads get stalled. Nothing has happened in the past hour, even though the expected time laps between is around 5 minutes. I had assumed yesterday job had crashed because of too many errors (bad source) but today’s one is stalled too and...
* ...uploads may resume. My batch of yesterday was blocked in the night ; before resuming today.

Is this normal behaviour? Anything I can do to make it easier for the toolset?
