Hi,

2 days ago, 6513 (17, 274, 51) failed (Bad WU) and it won't upload. I'm using v7.

Here's the log data.

The last line means: No connection could be established, because the target computer denied the connection.

I think this might be the same problem reported here: https://fah-web.stanford.edu/projects/F ... ticket/615. Two days ago did you get BAD_WORK_UNIT (114) or was it some other error?

Oh, it was an EUE and not a bad WU. Excuse me!

Here's the log:

The 171.67.108.25 server is a collection server ... you WU is coming from 171.64.65.62.

Sorry, I don't know the difference between a work and a collection server. "Collection" sounds for me, as if it would collect the WUs and "work" as it would distribute the work to the folders.

But it's fact, that the WU doesn't upload...

Posted: **Sun Apr 10, 2011 1:36 pm**

The collection server is supposed (but it's not always working as expected) to collect WUs that can't be returned to their associated work server (because it's down or overloaded).

If you want some more information regarding the the Servers, you might what to read this thread -> viewtopic.php?f=18&t=17794

Thank you! But my problem is still there and I don't know, if it's a problem of the server or the client. Is there a way to delete a WU from the queue with v7?

There is a way to delete the WU from the queue, follow bruce's post to the letter (viewtopic.php?p=182589#p182589).

The sever appears to be in NOT ACCEPT mode...

It's possible it's my connection/proxy, as another user here is experiencing the same issue with an SMP unit.

WU 5797 completed. not uploading due to the sever(171.67.108.25) it is trying to upload to being in not accept mode. 11 tries as of this post.
I would post the log but it is too large, and too complicated by the v7 putting all the client info into one log.

restarted fah contol anf got his from the log

the work server says it is accepting, but I can't connect to it for some reason.

Can someone check whether the following work units have been updated?

Project: 6504 (Run 1, Clone 199, Gen 95)
Project: 6516 (Run 5, Clone 212, Gen 36)

Still getting the same send errors as in my previous post on these two, continuing to download and upload new work units successfully.

Posted: **Tue Apr 12, 2011 10:08 pm**

No data in the WU Database yet for both WUs:

No data back from query

So I have marked them for a follow-up.

Posted: **Tue Apr 12, 2011 10:24 pm**

Thanks Panther, it seems they're still being attempted to be uploaded to the server that is in NOT ACCEPT...

I thought maybe they had managed to go through but for some reason this wasn't relayed back to the client, but it just seems they can't get returned.

I don't think it's my connection, because other work units have been able to be uploaded.
