any news on or if the problem has/is beening solved for getting work units to upload on Boinc

I am getting wok units ok so my machine is still crunching away 

this problem seems to be very reminiscent of the early Days of Seti@home classic.

hope they can sort it soon  
From the main Boinc home page: "December 5, 2005 
We are experiencing heavy traffic on our data server. This is
preventing some result uploads/workunit downloads. We are working on
the problem. More in Technical News. "
 and from Technical News: "December 6, 2005 - 04:30 UTC 
With the influx of new users, bottlenecks were bound to happen. A
couple nights ago we started dropping connections on the
upload/download server (kryten). This server was also serving the new
BOINC core client downloads. We immediately moved the client downloads
onto the campus network which was ugly, as this added about 20
Mbit/sec of traffic onto the regular campus network. 
On Monday morning we fixed this by making the secondary web server
(penguin) the BOINC client download server. In its former life penguin
was the BOINC upload/download server so it already had the plumbing
and hardware to be on the Cogent network. So without much ado, we were
able to move the core client downloads off the campus net. But what
about the secondary web server? Well, another Sun D220R (kosh) wasn't
doing very much at the time, so we plopped apache/php on that and made
it the backup web server. Some people might be getting failed
connections to our home page as DNS maps need a while to propogate
throughout the internet. 

Meanwhile, we were still dropping connections on kryten. At first we
thought this was due to the upload directories (physically attached to
kryten) getting too large, as the assimilators were backing up (and
they only read files in the upload dirs). Upon checking half the files
in upload were "antiques," still leftover from server issues way back
in August. We will delete these files in good time. We increased the
ufs directory cache parameters on kryten but this didn't help at all.
So our current woes must lie in the download directories (kept on a
separate server) or some other bottleneck further down the pike we
haven't discovered yet. 

And while all this was being diagnosed and treated we actually started
the master science database merge. This is why most of the backend
services are disabled, and will remain off until the first half of the
merge is done (about 2 days from now). We hope the results-to-send
queue lasts us through this first part. Having these back-end services
off is actually helping kryten catch up on its backlog of work to
upload/results to download. 

More to come as we discover more about current server issues and
progress further with the database merge... "

Web pages are wonderfull things, but only help if you view them.
