Perhaps it could help the debugging process if you (temporarily) turn on some other logging flags. I'm afraid that I'll not be able to help analyzing the output, but perhaps someone else is. I did use the following flags:
	<log_flags>
		<file_xfer_debug>1</file_xfer_debug>
		<http_debug>1</http_debug>
		<http_xfer_debug>1</http_xfer_debug>
	</log_flags>

Gruß,
Gundolf

Most of the time the upload goes up to 1.09 MB when it stucks, so smaller zip files will upload without problems.


I don't know if this will help, but I had a similar problem a year or two ago. It turned out to be with a device called a Riverbed, which is a network caching server, which needed to be reset. This was installed to cut down on interoffice network traffic (a lot of it repetitive), but it was also set inadvertently to cache internet traffic, and started causing trouble with CPDN uploads. If you have one of these at your location, maybe it could be the problem.

Here is the debug-info for one upload try with all debugging switches on:
Perhaps someone can read this?
The error occurs at 21:57:41 after 30 seconds of transferring 1.09 MB data.

The debug messages don't mean anything to me, but I'm not too familiar with network problems.
I'm not having any problems uploading zips to cpdn.

so I think it has nothing to do with MY internet connection but with the upload servers.
Other uploads and downloads work fine with this proxy server and VPN, i.e. to Chess960@home.

On boincsimap I got the same problem that the upload (~ 25 MB) stucks after a while.
But on this site the next try started where the previous stuck, so the file has been uploaded completely after several tries.

On CPDN the next try starts most the time at the beginning so that I'm not able to upload the files completely.
Perhaps this could be the solution to do it the same way as boincsimap does or is there an error in this mechanism?

I made a strange observation today: when I throttle down the upload speed to 15 Kbps, I was able to upload all of the 7 files after a while and several tries.
Normally the upload speed with my home internet connection is about 95 Kbps.
Perhaps this gives you an idea what is going wrong with the upload.

So at the moment all files have been uploaded and I think that is the solution for the moment.

A server is out of disk space - when trying to upload final zip file #13 for task "v5q2". Error first appeared 7 hours ago.

But note that an intermediate zip file (#3) uploaded ok for task "v5me" presumably to a different server.

Is the target upload server name recorded somewhere in the BOINC files?

Pity there is no way to suspend transfers only without having to disable the network. Even better, suspending individual files so active servers can still receive other files (as in above example).
Server status all green (otherwise would have known which server is down!).

Yes. In client_state.xml
1st, search for the model name.
Then keep doing this, but look at the lines above until you see upload towards the right hand end.
Keep going until you are just past the relevant zip file number, then look at the 1st part of the upload line. This will have the server name.
e.g. oerc

Thanks, Les.

Now located the upload server URL lines in every zip file (in the file_info blocks). Should have known this.

The URL in the "file upload_handler" line (for the stuck task) does not appear to be included in the server status page.

viz. <url> http://boinc1.coas.oregonstate.edu/cpdn_cgi_main/file_upload_handler </url>

Did further searches using the "file upload_handler" string. Examples found:

<url>http://cpdn-upload1.comlab.ox.ac.uk/cgi-bin/file_upload_handler</url>
<url>http://uploader.oerc.ox.ac.uk/cpdn_cgi/file_upload_handler</url>
<url>http://uploader1.atm.ox.ac.uk/cpdn_cgi/file_upload_handler</url>
<url>http://climateapps1.oucs.ox.ac.uk/cgi-bin/file_upload_handler</url>

That's 4 from the 7 upload servers listed. All Oxford servers.

So zip files may go elsewhere then. Directly to the customer.

Next, I entered the entire URL in the browser and got this
<data_server_reply>
    <status>1</status>
    <message>no command</message>
</data_server_reply>

which may suggest the server is "awake"?

Then forced a file transfer...and it's going again...now finished. 3 cheers. Another one bites the dust.

Good, learned something new - remote servers (outside Oxford) may cause hold-ups (as servers do) but not reported on the status page.

Thanks again for pointing me to the server url lines.

I've added that one to the status page, although I can't guarantee that the result will always be accurate.

Looking in the client_state.xml file the server is http://boinc1.coas.oregonstate.edu/cpdn_cgi_main/file_upload_handler

Tried entering the URL in the browser and got:
<data_server_reply>
<status>1</status>
<message>no command</message>
</data_server_reply>

So server is up but forcing an upload does not work.

Good, learned something new - remote servers (outside Oxford) may cause hold-ups (as servers do) but not reported on the status page.


I've added that one to the status page, although I can't guarantee that the result will always be accurate.

Thanks, Milo.

I also need to report a problem with PNW uploads. I've had one retrying for two days:

Sat Sep 11 13:12:13 2010 Internet access OK - project servers may be temporarily down.

What bugs me about it is that I live 15 minutes away from Oregon State. I could go over and knock on their door if I knew who they were.
