Yes.

I only joined the render pool a couple of days ago, and in general I've
been able to download and process tilesets fine.  The problem seems to
be that I can't upload the finished tilesets reliably, the upload queue
almost always seems to be full.  The upload.pl code has a backoff delay
which depends on how many times the upload has failed with an upper time
of 600 seconds.

After a while when the queue is full the client render just spends all
it's time sleeping and only retrying every 10 minutes.  The request
timeout because they can't been uploaded in time.
