Is anyone else experiencing periods of time where they cannot upload any of their Milkyway results and are stuck with Upload Pending for a long time (a few times an hour).

I have 2x ATI 5970's devouring WU and at times they are unable to unload the results to the server. Collatz can tear up the work-units and return no problem nor does any other project I am attached to have a problem uploading. If I suspend network activity then resume 2-6 work units are able to be returned then is stuck at pending again. It clears out a few times an hour and does not have issues then will repeat.

I'd like to donate more to Milkyway, but I cannot keep my cards fed with workunits...

Let me know what you think it might be or if you need more details.
