I had a similar problem last weekend ... here's what worked for me:

Open FAHControl
Click on Pause
Exit FAHControl
Re-boot computer
Open FAHControl
Click on Fold

As a CPU only folder, i found out theres one interesting thing is the A7 project never failed to downloaded/uploaded.
currently most A7 WUs are assigned from A7 only server 128.252.203.9, but occasionally i got WUs from 155.247.166.219, sometime i got transfer failure from 128.252.203.9 but never got SINGLE transfer failure from 219 server for one month

My failure on the weekend was an a7 project ... unfortunately it happens to all projects regardless of the core. It does not happen every time and some will not experience it for weeks at a time or maybe never, but it's certainly a 'pain' when it happens. The fact is that the core has nothing to do with the download/upload sequences ... that's all done by the client.

This worked. thanks!

I tried stopping the fahclient and killing any remaining processes for user fahclient and then restarting the client but that didn't work in this case. Rebooting linux is not a satisfying solution for me but it worked.

There's a known bug in FAHCore_A7. It has been fixed in a new version of that FAHCore and that version is being beta tested so it should be ready to release soon. The bug causes extra (unnecessary) information to be added to the result, making the file too large to upload. Excessively large uploads are being rejected by the servers. (Yours is 68 MiB and it should be maybe 10 MiB)

I would probably discard that file, but it will eventually expire and delete itself from your system.

Most likely you have been processing that WU with the "on idle" setting. I recommend you discontinue using that setting until the new CPU FAHCore_a7 is released.

I concur - looks like the download issues are back with the 155.247.166.* server.

I am down on two out of four Folding machines. I will keep them down until/unless someone can give the "all clear".

What messages are you seeing when .219 doesn't issue a WU?

=====

The bug in the CPU FAHCore_A7 has been fixed so all CPU Wus going out now will no longer be inflated ... consuming extra bandwidth. Over the next couple of weeks, those CPU WUs that are being processed will be completed and the congestion problem will gradually be reduced.

Same. I've been getting hung folding slots for the past 4+ hours. Downloads fail from *.219, and just stop like this:

Both of my 1070s were hung on 'download' this morning. 155.247.166.219 needs to be pulled until the underlying problem can be fixed. It's been over a month intermittently now. This is not a good look for the project.

I don't think there's any chance that the server will be pulled. vav3.ocis.temple.edu is currently supporting about 25% of FAH''s activity. Taking that capacity off-line would make a huge disruption in your ability to get an assignment when you need one. I understand it looks bad, and is an inconvenience for you but that's unrealistic and makes a moderate problem into a big one. New hardware is being ordered to handle the recent increase in production, but provisioning for that increase takes time and money.

Besides, the first step has been completed (fixing FAHCore_a7 software) and rolling out that fix takes time because it's cannot be called "completed" until all WUs currently in the field are refreshed with new ones, no matter how slow the Donor hardware happens to be.

Wow, 25%, I thought the load was more distributed than that. These issues don't bother me that much, but the hanging downloads require manual intervention on our behalf, and for folders which don't (or can't) check their systems periodically, it results in lost output. I'm hoping the next client release supports a hard timeout on downloads, which would help a lot.

My 25% number came from https://apps.foldingathome.org/serverstats.

There are a lot of servers currently off-line, and don't know why. (Possibly related to a recent critical upgrade of the server software)

The essential part of my post is that the problems are understood and are being addressed --- and it takes a lot of "red tape" to get enough signatures to spend as much money as it takes to get a new server(s).

Also probably related to servers no longer being operated out of Stanford, the last one was shut off in the last couple months. That leaves servers at WUSTL, Temple and MSKCC.
