155.247.166.220 downloads stalled

[info2x]

Still happening as of this morning.

Failing as of 1730 UTC but I got redirected elsewhere pretty quickly

When I open http://vav4.ocis.temple.edu I do see the server's landing page but it refreshes very slowly. I'm guessing that the campus networking problem mentioned above is still un-solved.

Yup, for the last 3 days pretty much every stuck slot has been a result of a download stalling from this server. It's nasty in that the download starts and progresses a few % then stalls which then seems to block the algorithm used to detect stalls. I was on the new client (7.6.9 & .10) and rolled my systems back to 7.5 with no improvement.

Just checked all 15 of my GPUs and not a single one is running a WU from this server.

I observed that if the download is progressing slowly and the current WU completes and starts uploading that seems to cause a stall. So I backed the next-unit percentage off to 95% but that didn't seem to improve things.

What I've been using in Ubuntu to un-stick the slots is:

1. Pause all the slots on the system
2. execute:

Code: Select all

sudo service FAHClient stop (but this does not cleanly stop the client ... so ...)
ps -ef | grep fah (and note the Process ID (PID) of the fahclient)
sudo kill -KILL <PID>
sudo service  FAHClient start

I've been fighting this same problem off and on for at least 2 weeks. Get the Connecting to 155.247.166.220:8080 line and then it will either just sit there forever (or until I reboot) and wait for information to be passed, or it will send me a pittance and then sit there forever (or until I reboot).

Could a NO activity timer be installed some where that would cause it to abort and try again?

Apparently after the server stops sending data it aborts at that end, but doesn't transmit the abortion to the over end.

[Kjetil]

I have no problems 155.247.166.220. but i am on beta flag.

Ahhh ok. Thanks

[CKWarner]

We're working on the problem. We've seen similar problems before -- they might arise from how the server code deals with stale connections, compounded with network issues on campus. We have restarted the server code; let us know if the problem persists

I'm still getting stalled downloads, and not just from that one server any more.

Welcome to the F@H Forum CKWarner,

This is my thread already.

It seems to be only GPU WUs that stall. The log isn't super helpful at the time that it happens, given that it's just showing the percentage and then nothing, although the timestamps could conceivably be useful I suppose. Here's a stall from yesterday, coincidentally from the server in question:

About five minutes later I did the delete the GPU slot procedure I listed earlier in the thread to get the client folding again.

Here's the configuration gubbins from the start of the current log:

...This is my thread already...

Apologies... I scrolled a few posts up and saw various other logs hence the suggestion.

...It seems to be only GPU WUs that stall. The log isn't super helpful at the time that it happens, given that it's just showing the percentage and then nothing, although the timestamps could conceivably be useful I suppose...

In this case, it was useful as it showed that you encountered a known issue where failure in network connection will cause the client to hang-up (https://github.com/FoldingAtHome/fah-issues/issues/983). Rather than removing the GPU Slot and adding it back in, it would much quicker to restart the client or your system depending on what is easier.

Still having the stalled downloads from this server. but it does seem to be improving.
Mon 8 of 9 stalled
Tue 7 of 9 stalled
Wed 5 of 9 stalled
Thu 3 of 9 stalled

This when I checked them right after getting up after a nights folding.
