I'm seeing this frequently and uploads are slow, I've got a large backlog
that is slowly uploading but not keeping up with my crunching. Downloading
is also just as slow. My other internet traffic seems ok (web browsing
email etc)
Any idea how to diagnose whats wrong here?

Here are some sample messages:

Wed 26 Dec 2007 04:14:54 PM PST|SETI@home|Temporarily failed upload of
31dc06aa.23307.1299.4.6.191_2_0: http error

And also another sample:

Wed 26 Dec 2007 03:48:31 PM PST|SETI@home|Started upload of
09no06ac.11950.73.11.6.185_0_0
Wed 26 Dec 2007 03:49:51 PM PST|SETI@home|Scheduler request failed: HTTP

Wed 26 Dec 2007 03:52:08 PM PST|SETI@home|Finished upload of
09no06ac.11950.73.11.6.185_0_0

I'm running:
  BOINC 5.10.28 
  mandriva linux 2008.0 kernel 2.6.22
  Q6600 Intel system, in 64 bit mode

Thanks
