Ha, well, one of these is in a cold garage, and the other in the house, where we are performing our annual ritual to see who gives in and turns on the heat.

My linux dual 1080Ti rig stopped folding a couple of days back. I haven't stopped the client yet so I still have the log files "frozen in time". It looks like both stopped due to downloading issues from each of the 2 servers from Temple University.

Anything else you'd like me to check before I restart F@H?

I don't know what I don't know! For the race, I just with there was a way for the system to trip an alarm when this happens, it's a busy time of year and potentially millions of ppd could be at stake.

Use This:

And you only have to check one computer, and click on each client for "running" and ppd. It takes 30 seconds total, and I do it 3 times a day or more. If you are in a real hurry, sometimes just looking at the total farm ppd (lower left corner) will tell you if a box is not working correctly.

Edit: the above works in windows or linux, with clients mixed. In the above, its running on windows, and 8 of the 12 are linux.

In the meantime, is there a better method to keep tabs on these GPUs and be warned when they fall idle?
Click to expand...
A script could check periodically whether FahCore is running. If it doesn't for more than e.g. one or two minutes, the script could killall -9 FAHClient, then restart the service. (Multi GPU hosts require extra consideration.)

Another but unproven idea would be to blacklist the offending work servers in a firewall rule.
 
Both suggestions have merit, gentlemen. In the meantime, I am continuing migration to Linux (terra incognita for me). Hopefully by race time either or both solutions can be implemented!

This script does something different from what I suggested. It reboots.* I for one would not run something like this.

*) ..under a variety of circumstances. Under other circumstances, it does other things. Since it has literally a dozen purposes, it is highly convoluted. I believe in shell tools which do one thing, and do it well.
 
@StefanR5R, I suppose I ought to at least say please! 😳

I should be more ambitious and try to learn to do it myself, like I did when I was younger. But I suspect the learning curve would be pretty steep. Over time, studying what you present is helpful though. Thanks!
 
OK, it just happened to me. It was an error I have never seen before, but I can't find the log file now. I just rebooted and BAM, all is fine.

Something about a timeout, multiple times.

Edit, but after it started up, its unit 14230, the ppd calcultor knows nothing about it, and its doing 180k on a 2080TI which normally does 2.2 million ppd
 
Last night before I went to bed I checked my dual 1080Ti rig and found one GPU had stopped/hung during a WU download but the other GPU was still working normally. I was too tired to do any detective work so I committed a linux user cardinal sin and rebooted the rig and went to bed. This morning I did some searching and found the "parent" fahclient process ID is logged in /var/run/fahclient.pid.

I was thinking a monitoring script for a single gpu rig would be more straightforward than a rig with multiple gpus. For a single gpu rig, a script could monitor changes in the log file (/var/lib/fahclient/log.txt) and if no changes are detected after 15-30 minutes, then kill the primary PID and restart the client. That would not work in a multiple gpu rig since all the clients write to the same log file. Detecting one "hung" gpu in a multiple gpu rig is a more complicated problem.

Correction: There are log files for each slot too. In my dual gpu rig with 2 gpu folding slots:

/var/lib/fahclient/work/01/logfile_01.txt
/var/lib/fahclient/work/02/logfile_01.txt
 
biodoc said:
/var/lib/fahclient/work/01/logfile_01.txt

Apparently these directories are unit #'s rather than slots. Now I'm seeing:

/var/lib/fahclient/work/00/logfile_01.txt
/var/lib/fahclient/work/02/logfile_01.txt

Lol, it's more complicated again. Directory 01 was replaced with 00 when a new WU was started.

Two out of three of my Linux F@H clients were stuck this morning. One of them is single GPU, the other dual.
Click to expand...

Bummer. 🙁 I'm also running WCG on 18/20 threads with 2 reserved for FAH GPUs. I was wondering if boinc uploads/downloads was competing/interfering or taking priority over FAH downloads so in FAHControl/configure/advanced I switched "folding core priority" from "lowest possible" to "slightly higher".
 
I'd worry about a possibility of home networking stalls if LHC@home was on. But since Mark & Mark & Jon & presumably others experience this problem, it's certainly rather a networking problem near the F@H servers, as has been alluded to in a forum thread which one of you found earlier. (That said, it's a bug in the client if it hangs when a download stalls, instead of trying to recover e.g. by a new work request.)

Monitoring F@H log files could be useful, if there was a way to unjam F@H not by restarting it completely but by kicking only those subprocesses which are associated with a specific slot.
 
I was looking through FAHClient --help output and found this one:

respawn <boolean=false>
Run the application as a child process and respawn if it is killed or exits.

Do I dare add "respawn true" to the client options? The description makes it sound like it's difficult to stop if necessary.

The output of 'ps -u fahclient f' would be useful I think for that purpose.

Bringing this thread back to the top again because I have a new problem. An X99 2676v3 Mint box in particular that has two 1070's in it has a FAH problem where the WUs appear to get stuck at 99.99%. Trying to stop and restart the client does not work, and "kill -9" does not work either. This is what I get after trying to kill the client(s):
Code: 
c7x99@c7x99-C7X99-OCE-F:~$ ps -A | grep FAH
1820 ?        00:00:18 FAHClient <defunct>
1822 ?        00:02:26 FAHClient <defunct>
3574 ?        00:10:37 FAHControl
What I have learned is that the client has become a zombie process, possibly because of my overzealous use of kill -9, or some other reason. using "ps j" to determine the parent process of the zombies returns value "1." Since 1 is "init," and the processes stay this way indefinitely, it means I have to reboot at this point , since init can't be killed, and FAHClient can't be restarted while it's zombie-self "lives" on. A curious thing is why there are two entries, I will have to keep an eye on that to see if there are two when it's running normally.

Edit:
When running "normally," there are two FAHClients. The parent of the first is init, the parent of the second is the first FAHClient:
Code: 
c7x99@c7x99-C7X99-OCE-F:~$ ps -A | grep FAH
