HTTP 503 error - backend error

[Mr-Si]

Hi there,

I am getting the following error reported when I am trying to do my Gsync'ing.
It occurs overnight after having been uploading files all day (first time upload)
So I then re-run the command.

The command I am using is:

gsync -c -r -t -p -o -g -v --progress --delete -l -s /data/source/ drive://destination

The error I get (after many hours) is:

DEBUG: 'Exception': File "/usr/local/lib/python2.7/site-packages/libgsync/drive/init.py", line 704, in update

I am unsure of how to debug this. Our limit is the 1TB limit and we have not hit this.
