Message 552278 - Posted: 24 Apr 2007, 10:16:25 UTC - in response to Message 552258.  

Hi.
For last couple of days I have been having upload problems on only one of my computers. On this machine I have 4 stuck uploads (WUs dated Apr. 22nd), while downloads and scheduler contacts happen without a single glitch. Unfortunately I don't remember reading anywhere, how to "unstick" these uploads (IMO it has to be a problem with partial file upload).
TIA,

Could you post some lines from the message tab, please, to show what happens when it (re)tries to upload the results?

I tried to do some troubleshooting a while back on messages which looked like:

Error on file upload: Socket Read incomplete: asked for [a lot of bytes], received [fewer bytes]

- which may look like a partial upload, but in fact turned out to be a complete upload of a smaller file: for some reason, BOINC had completed computation of a WU, signalled it was ready to upload, and then re-started computation of the same WU - overwriting the results file in the process.

If that's happened to you, I don't think there's any recovery possible - just abort the uploads in the 'Transfers' tab and move on. But best to get a second opinion on the messages first.

Thanks for a swift response.
As soon as I get home I will paste those log messages, but as far as I can remember all they say is http error. Symptoms are these: if I retry upload, there is a message: "retrying upload of ...", then a pause of couple of minutes (during which upload status reaches 100% in fist few seconds, transfered bytes are even greater than filesize by some 100s of bytes - around 0.5k greater) and after that http error, followed by reference site check (checks ok.) and a message: "contact to reference site ... project may be down". Will also try using a proxy.

BOINC 5.4.11 on C2D e6600, 2GB ram, WINXP SP1, connected to ADSL 2048/384 through router.

Success.
I set BOINC to use a proxy and all uploads went through.

Error on file upload :no command ??
Server rejected file, but it has Validation error?

Not logical to me. To be rejected I can accept, why I wouldn't have a clue. and to issued another copy to another host seems logical. But to go through validation, not logical.
If it was rejected and it can be communications error, but would not be there for validation.
It could have been partially received, missing the EOF marker, or of incorrect size. Go to validation and be designated invalid.

below is relevant msg's

The workunit is 126901614

Note green line that is at 65 hours 24% complete, if this problem happened to a unit like that, I cam see some very seriously upset people.

“You pays your money and you takes your chances” with beta projects—and even with some that aren’t (but maybe should be) … I’ve wasted hundreds of CPU-hours’ worth of effort for one reason or another beyond my control. It’s disappointing when that happens, sure, but “very seriously upset[ting]”? How would those people react to loss of a job, breakup of a relationship, or a death in the family? ;)
