After the stubborn server problem last weekend was fixed and all the WU's started being accepted I had one that didn't send and gave me some message about a problem with unit.

As you can see the first WU is sent successfully but the second encounters a problem. What's the problem with WU and is there any way to fix it or is it lost?

Here is where I first downloaded the WU in question.

Folding@Home Client Shutdown.

We've never had an official explanation of "...problem with a unit" but my best guess is that something was corrupted somewhere along the line and the server is saying that the WU does not pass the validity tests for accurate scientific results.

I'm not aware of WUs being accepted after they've gotten that message, but I can't see any reason to discard it until it has tried to upload a number of times. Eventually, you'll probably have to just discard it or wait until it expires and deletes itself.

Well it was worth a shot. Thanks bruce.

Bruce, I've received the same message this weekend, for 3 or 4 WUs. They were from different clients/pcs, the only thing they had in common were the Work Server (108.33) they came from. After my client received this message, it marked the WU as successfully uploaded, and thus I could no longer try and upload it. One time I took a complete copy of my directory, and tried uploading it; same result every single time...

Must have been on the server's end, as I've never had that message before, and when the server was having trouble I got it on all 3-4 Wus I had pending from that server...

Thanks for the report. We'll look into it.

How did it mark it as successfully uploaded? Mine I think deleted the WU after the server problem message. The slot where it was worked on in queue was then labeled empty/deleted.

Posted: **Thu Nov 04, 2010 4:51 am**

Successfully uploaded or not, the queue will always say "empty/deleted". For the first of the WUs I lost this way, I still had the work files, but it was removed from the queue; so I looked into the 3rd party tools if there was something that could generate a new queue. One of the queue information programs can output a whole lot more information than starting the client with "-queueinfo" can, one of those lines said that the WU was successfully uploaded. No luck recreating my queue, though; the only program that did that works only for v5 clients... (Afterwards I figured out that even if I had been able to recreate my queue, the server would've thrown the WU out every time I tried uploading it anyway).
