Well, the upload issues are gone. My server (and BS) have been up and running now for 8 days, 4 hours, non stop. Uploads are at 16,079. Why did it start working again? Not a clue. It started again just as mysteriously as it stopped. Troubleshooting narrowed it down to a BS problem, as Limewire would run fine on the same machine, but BS would just sit there and flail. Even tried different versions of BS, and would get the same (non) results.

So, I know this about it:
- it's not a provider issue. If it were, then Limewire wouldn't work, either.
- It's not a system software or net hardware issue - see above.
- I *suspect* it is something in Gnutella that is targeting BS specifically, but I know of no way to detect that. I've heard that Free Peers used to be able to exert some measure of control (or interference) with their software, so maybe the mechanism is still there.

If any of you out there are encountering similar problems (people sporadically not being able to get files from you), let me know, and let's compare notes.

Thanks

Nick
