Folding Forum

Posted: **Mon Mar 16, 2020 7:40 pm**

Hello,

I'm new to Folding@home, so I apologize if the solution here is obvious/trivial.

For about the past ~15 hours maybe, I have 2 FAULTY WUs that are failing to upload.

All NO_ERROR WUs continue to upload just fine (with the occasional hiccup, of course, due to the unusually high volume). I have uploaded ~20 something NO_ERROR WUs today, so only these 2 faulty WUs seem to be affected.

I would like to be able to somehow drop these FAULTY WUs (with or without credit) so that somebody else can start working on them. Right now, I appear to just be holding them (until they time out, I suppose).

FAULTY WUs that won't upload:
11758 (0, 3765, 0)
11759 (0, 10513, 1)

I have checked the WU Status for each of these units (above links) and it looks like nothing has made it back to the collection servers.

A Project search for 11758 says Project Unspecified.

A Project search for 11759 leads to a valid covid project.

In most instances upload fails immediately:

In other instances, upload will make it to maybe 0.20% and then fail:

I saw the qfix instructions posted in the Troubleshooting "Bad WUs" sticky, but it appears that qfix (last update Jul 5, 2012) now only applies to v6. This particular node is running v7 (i.e. no queue.dat). I'm guessing the v7 client picked up this functionality natively since v6.

I have paused/restarted folding and restarted the FAHClient service on this node a few times, but to no avail.

Any advice would be greatly appreciated. Is the best course of action to just hold these failed WUs until they time out (or hopefully upload)?

Thanks in advance!

Folding@home Core Shutdown: BAD_WORK_UNIT

Posted: **Mon Mar 16, 2020 7:57 pm**

The servers are struggling to accept all the work units that are being sent in. I would just leave it to continue to try and upload, you do get partial credit for a failed WU so its still worth it going back.

That doesn't be to seem the case for project 11758, it looks more like some kind of configuration issue than an overload issue.

I have 2 units that are stuck like that, not being able to send the results for almost 48 hours in one case, and almost 24 hours for the other. Both from project 11758, both on servers 155.247.164.213/155.247.164.214:

Looking in other threads discussing this issue it seems only one or two projects from those servers are affected, the rest are working fine, suggesting it's not an overload issue.

I ended up uninstalling and reinstalling after getting stuck on 11758 for 24hrs. Hoping I don't get it again until it gets fixed. Until then, it seems to be working "fine" now.

Interesting. Good to know I'm not the only one having an issue with Project 11758

32hrs since my original post, and my client is still attempting (unsuccessfully) to send these two "problem child" failed WUs:
11758 (0, 3765, 0)
11759 (0, 10513, 1)

It doesn't seem to be jamming up the works though.

I am still receiving and running new WUs no problem. Sending completed NO_ERROR WUs is also still not an issue. Submitted ~53 WUs so far today, yet still these 2 failed units refuse to upload

Looking at the Project Summary page, it seems like the deadline on these jobs is 8.2 days.

I still hate the thought that my client continuing to hold the lock on these WUs will delay the computation of the associated frames by 8 days.

Wish there was a way to release these so somebody else could work on them (hopefully without error).

Also having problems with the same project. Refuses to upload.
Trying to follow the project link gives you an error, saying there is no project with that number.

Had a 11758 fail for me as well.

The fact that 11758 (0, 3765, 0) cannot be found on the server probably means it has never been uploaded.

Regarding 11759 (0, 10513, 1) the WU has now been successfully completed. I don't know if either of these reports happen to be yours but the completion suggests that the problem might be on your end. (Marginally stable overclock or something else

)

Code: Select all

SamGamgee 	Faulty 2
Mrukson 	Ok

Unfortunately, I don't know the difference between Faulty 2 and any other type of FAULTY.

One possibility: "transfer failed" generally means that the result file was somehow corrupted. Do you happen to be running an antivirus scanner?

Some folks have had scans pick up a string of random numbers that somehow matches the pattern of some malware that has been found installed on other computers. This false positive is probably followed by the quaranteen of the offending sequence ... leaving some incomplete data to be uploaded. The fix is to configure your scanner to avoid looking at FAH's work files.

Still can't upload my 2 GOOD WUs from 11758, getting close to 72 hours since I finished the first one. Before the last attempt I even disabled Windows Defender, the problem persisted:

It would be nice if the servers could report more helpful information to the clients when such errors occur, so that it's easier for everyone to troubleshoot the problem.

Actually, I think the error messages are a bit cryptic for two reasons.

1) there's probably no more information available. "Transfer failed" (or whatever) probably doesn't have any more information than the fact that there was a communications error.

2) FAH doesn't want to aid hackers. Most other distributed computing platforms have been plagued with cases of people trying to earn more points by trying to upload falsified data. FAH has had relatively few cases like that, but it has happened. FAH SHOULD NOT be telling those people how it detected that the data was falsified so they can improve their ability to construct better crafted false data.

Posted: **Wed Mar 18, 2020 8:05 pm**

OK. As long as it's not a systemic issue, 2 stuck units here and there probably won't make much difference in the grand scheme of things.

So maybe it's not worth the effort to investigate this further.
