since several days I have problems uploading the data.
I get these messages when uploading three different results:

Any ideas?
These messages are the same since a week or more. On other servers there are no problems.
Also with other projects there are no problems in uploading.
I'm not using a proxy.

Hi Legolas

I had a lot of files to upload yesterday. Most uploaded immediately but some produced messages like:

28/07/2010 00:05:32|climateprediction.net|Temporarily failed upload of famous_u0d0_599_200_006633319_3_9.zip: HTTP error

But the files uploaded successfully 5 or 10 minutes later.

Have you got files stuck in the Transfers tab that cannot upload?

---

Cpdn news

At the moment there are 5 files in the transfer tab, which are to be transferred.
The upload goes to a maximum of 1 MB when it stucks.
There are 3 hadam and 2 famous WUs to upload.

I had the same from time to time but in the past the upload was successful after several tries.

---

One point:
I have two other machines where the upload is ok with client version 6.10.56
The machine that fails has 6.10.58
Can that be the reason?

---

I don't think the computer's Boinc version can be the problem. I have computers with 6.2.19, 6.10.56 and 6.10.58; they all upload files. But on all three computers there are occasional problems with CPDN HTTP and other server errors. They could be various messages for the same server problem.

CPDN server status is all green. Check that the computer has Network activity always available in the Activity menu. Instead of waiting for Boinc to try again press the Try again button in the Transfers section and see what happens. I would use this button at intervals but not dozens of times repeatedly. Once each time.

Cpdn news

That machine is at home - at the moment I'm not there.
But I did that yesterday evening and each time it started uploading with the expected speed of my internet connection and suddenly it stucks after about 1MB uploaded.
Is there a possibility to restart the upload servers although the status is green?
I read in another thread that this solved the problem a few months ago.

---

The number of results to be uploaded is still growing: now I have 8 files waiting for uploading. They all stuck after 1 MB.
what can be done ? :-(

---

Does anyone know when the uploader.oerc will be back up? I already have a 2 zip files stuck in the transfer tab, and will have 2 more by morning. In the meantime I have suspended network communication. I guess that all we can do is wait for the data transfer to be complete.

I've got two files stuck:

Now those've been lingering for few days now. Is it because uploader.oesc being down or are those task just messed up?
Other uploads went ok.

Please read the post about uploader.oerc in the forum News thread at the top of this Number Crunching section. As soon as we know more that is where it will be announced.

The uploading is not really better although all upload servers seem to work.
In the meantime two files of FAMOUS 6.11 were uploaded but still 5 files stuck after about 1 MB.
And I have still 2 HADAM and 1 HADSM file to be uploaded - also stuck after about 1 MB.

Here the messages with xfer-debug:

It may be something external to your computer:
ISP limit
Business/Educational institute file size limit, or data amount limit.
Proxy server problem.

Or if you have your own router/network, something with that.

Backups: Here

I don't know much about network problems but wonder whether trying this could help:

http://setiathome.berkeley.edu/forum_thread.php?id=47636&sort=6#768589

[Edit: Don't do that yet; just read it. I've sent a message to Gundolf on Seti asking whether he thinks trying that would be a good idea.]

---

Cpdn news

That's what I had in mind, but was going to wait and see, before explaining about cc_config.

There may be another member with the same problem plus a person who seems to have the same upload problem on the CPDN Beta project.

Legolas, we don't need to know the model names or task numbers or workunit numbers for the files that cannot upload. But could you please tell us for each file:

* the model type (eg HadAM3P, HadSM, FAMOUS)
* the version (eg 6.10, 6.11)
* the file number (that's the number like _11, _13 at the end of each file name in the Transfers tab. Not the number at the end of the name in the Tasks tab.)

When we know that we can look at our list of which files upload to which server to see if it's a problem with one upload server or more. Please list all the details for all the files because some models upload files to 3 different servers(!).

Cpdn news

I've had a reply on Seti from Gundolf who says:

The symptoms Legolas describes are different from what I have experienced, but he could try the other protocol nonetheless. I can't imagine any problems being introduced by doing so.

I am running HTTP 1.0 for several years now without problems (SETI and Einstein). My problems were probably caused by my ISP.

Legolas should also try a reboot, to flush all (DNS) buffers of unwanted information.

* If you haven't rebooted since this upload problem began try that first.

* If the files still don't upload use Gundolf's suggestion in the Seti forum thread. Before you edit the cc_config file you should completely exit from Boinc by right-clicking on the Boinc icon and selecting Exit.

* If that still doesn't work it would be useful if you could give us the information I listed in my last post.

Cpdn news

Thanks for your answers.
I will try your suggestions this evening.

I did already a reboot since the problem occured first and I also rebooted my rooter. That didn't help so far.

---

I tested the HTTP option and it had no effect :-(
and I also booted my machine.

Here are the models, versions and filenumbers ( 3 different WUs ):

1. HadSM3 6.07 File _1
2. HADAM3P 6.14 Files _1 and _2
3. FAMOUS 6.11 Files _2, _3, _5, _6, _8

The HadSM3 and HADAM3P WU has already been finished.
The FAMOUS files not in the list had the same problem but at least they were uploaded.
Can you see an error on the server when files are uploaded?

---

Well, you are trying everything.

I can't see the server, nor can any of the other moderators. None of us are in Oxford where CPDN is. Milo, the programmer, can see the servers. But now it's his weekend.

I was hoping that all the files would be allocated to one upload server and Milo would find a problem on it.

But if our upload server lists are correct, HadSM, HadAM3P file _1 and FAMOUS files _3 and _6 go to uploader.oerc, while HadAM3P _2 and FAMOUS _2, _5 & _8 go to upload.1.comlab. If the FAMOUS 6.11 is from a new enough batch all its files will go to kraken. So two or three upload servers need to accept your files.

I think this must be some connection problem at your end. I would be surprised if it's a bug on two or three upload servers. While we think again about this, don't constantly retry the transfers in the Transfers tab. I think the number of upload attempts allowed for each file is 100.

But other files have uploaded OK?

Have you got another computer there with internet access? If so, does it crunch CPDN and do its files all upload?

Cpdn news

I have 17 other projects running here all of them without upload problems.
And I have no other computers here, only at work which upload without problems too.
I upgraded to Boinc client 6.10.58 a few day ago.
I will go back to 6.10.56 but I don't think that will help.
It's a try.
Most of the time the upload goes up to 1.09 MB when it stucks, so smaller zip files will upload without problems.
I crunched a lot of CPDN WUs without any uploading problems.

It doesn't matter if the problem is not solved over the weekend if we can get a solution one time.

Have a nice weekend.
