171.67.108.22 was overloaded. Dr. Pande said he would look into it. About that same time, it stopped being overloaded and a number of WUs have been uploaded since then.

Your log shows an upload attempt from before the problem was corrected but your client has not retried since it was fixed.

It uploaded the P2684 WU about 14:00 PDT. Thanks for looking into it.

Successful uploads are running about 20 per hour. Does that server respond to http://171.67.108.22 or http://171.67.108.22:8080?

When I open those URLs, firefox does not display the OK page, but it can download a file containing <html><b>OK</b></html> which is correct. (You really don't need to do that as long as you don't get an error message.)

[Probably not Stanford server but OS X and Wine]
2684 WU never successfully uploaded to this server and neither was the the the following 6900 WU uploaded to its Work Server. When I was assigned another 2684 WU I stopped. Each of the WUs, on completion and subsequent upload attempts would fail to completely upload. The sending would stop after about 10 minutes and on this machine normal uploads each took 18+ minutes. True since jan-8-2010. I'll miss the 1,000,000+ point months and hope for a Mac native bigadv client.

The has been only one recent change, OS X 10.7 install on day of release. Best guess is that Wine under 10.7 does not work well. I do not have the ability to diagnose the error. Installed Virtualbox and now folding with Ubuntu 64-bit 2.6.37-30, "-smp 16 -bigadv -verbose 9". A 6900 WU is running at about 3.33 x min with ~27 min frame times. Hopefully the upload proccess will succeed.

I have been unable to upload to this server for 2 days now, and I am almost finished with another WU. It also appears to use a reject server as the backup. I have never had problems with this computer uploading before, and I have other machines on the network uploading whatever WU fine. The status page lists this server as full Accepting. I seem to be able to ping fine and visit the folding@home pages fine as well, is there anything on the server end, or must it be on my end?

I've merged your posts with an ongoing topic on the same server. It's possibly the same issue that has been discussed earlier in this new topic. I'll make sure the Pande Group is aware of the issue.

The issue with Collection Servers which are supposed to be there as a backup is a long-standing problem which is moving (slowly) toward a final solution.

TarogStar · Post by **TarogStar** » Fri Sep 09, 2011 2:31 pm

The WU finally sent today, after losing all the bonus points. Is that server overworked, or did the Pande group do something to fix it? I have another WU from the same server due to be completed in about 14 hours, is there anything I can do on my end if this happens again? Do I just need to keep trying to resend that unit over and over by restarting the client until it sends? It looks like that server has been accepting WU the whole time that I couldn't send them...

Post by **bruce** » Fri Sep 09, 2011 3:54 pm

There's really nothing you can do on your end.

On Sunday-Monday of this week there were some problems with both servers 130.237.232.141 and 130.237.232.237. (See other topics in this forum.) Those servers distribute similar projects to the ones found on 171.67.108.22. To fix the problem, one of those servers needed to be taken off-line for a few days. With all servers functioning normally, they run very close to optimum capacity, both providing good service and using server resources wisely. With one server off-line, the remaining servers attempt to handle the additional workload but the workload is a challenge for them and the service level suffers somewhat.

Post by **bruce** » Tue Sep 13, 2011 6:07 pm

If uploading to the primary work server fails, the client is designed to send the data to the collection server, whether that collection server is operational or not. Nobody can do anything about that part until the new collection server code is fully operational.

As far as whether the communications problems between you and 171.67.108.22 are concerned, I have no way to determine if the problem is in your installation, with your ISP, with Stanford's ISP, or with Stanford's server . . . except to check that the server is actively receiving projects from others. During the past three hours, the acceptance rate for uploads has been about 10 WUs per hour. By itself, that number means very little (unless it's zero) but over 24 hours, it does seem to vary between 4 and 17 so I'd have to guess that's pretty close to the rate at which these projects are being completed.

This WU was reissued and somebody else has completed it so as far as the science is concerned, the WU has been completed. For you to get credit, though, your copy will need to be successfully uploaded.
