Looks like I am getting about 30% "Error while Downloading..." on three computers. When checking the other results of the same work units with other members of the project it show the same results.

Hi Yank,


I've invested in several "larger" systems and I've just looked at the results for this one system. I've got 1200 "error while downloading" too!!!

Is this only during download maybe? Or is it jobs which has been done? I know downloads is new jobs, but my jobs done has declined during the last month. This even though I added another new system/cruncher with additional GPU's ;) !?!?

And it's not just one box, it's all of them. Have you heard anything???

Error (1200)
errors Too many errors (may have bug)

CPU's i5-4690K
GPU's GT640/GTX750TI

Is this only during download maybe? Or is it jobs which has been done? I know downloads is new jobs, but my jobs done has declined during the last month.

Yes, if you see 'Error while downloading' the task never reached your computer so it can't be "jobs which has been done"

About "declined during the last month" it have to be probably in "the last week"

See the list of your tasks and look in the 'Sent' column.
You will see a 'gap' of no (or very few) tasks in the period ~10-16 Oct 2014 (server had no tasks to send for everyone)
and also many of "Sent" files give 'Error while downloading' which may be because:
- file do not exist on the server (or is in wrong directory, or have wrong filename?)
- server was overloaded (network/database/disk overload):

If you (everyone) have no tasks to work on - no wonder your (everyone) RAC go down.

Hi Bilbg,



Thanks for your reply.

If you (everyone) have no tasks to work on - no wonder your (everyone) RAC go down.

I think that when the systems are going to run more than 30 days without interruption, that the numbers will increase ;)

I've got some WUs with that problem and decided to take a look at forums to see if there's any help, and I see that i'm not the only with this download error, maybe is a server bad configuration. Any suggestions about how to solve it?
Edit: About 2 atempted WUs both failed

End result I a lot less than 17 tasks ready to crunch, and a fair few messed up downloads.
I've set NNT for the time being I'll resume and try again later.

The problem is NOT on your end, so is not fixable by you.

Looks like you need a server application to inspect every workunit, and if any of the input files are not in the right places on the server, mark that workunit as Download failed without actually sending it out to any clients.

I might volunteer to write it, except that I suspect that your server uses Linux, and I've never used Linux at all.

I am NOT an admin, I am just reporting what I see like everyone else, the problem seems to be in the transmission, whether that is a bad file being sent as you say or a bad connection along the way or even because of too many connections at once is beyond my expertise to figure out.

I do know that Kyong is aware of the problem and seems to have settled into the fact that it is going to happen and has learned to live with a certain number of failures. As I said before the Server will automatically put the workunits back into the queue to get resent to someone else, so no work needed on his part.

Hi, I am aware of this unfortunately I am now solving another problem. I am changing my job and I have now temporarily 2 two jobs at once, so it is very complicated for me now. Since January, I will have just only one job, so I will be able to take care about the server much more again. I am sorry for it. I will try to solve the problems with download errors as soon as possible.
