Well my Ryzen has been up for 4d-1h since the PSU swap out, possibly that cured that problem. But only long term will tell for sure.

I wonder about that C-state mentioned. I occasionally (rarely) see my CPU use drop to 0 for a few seconds, then pick right back up. This might be the cause of the errors I'm getting. Maybe ...

The file deletion problem has been around for quite some time. Take a look at the yearly graphs for that. I mentioned it to Eric in the News sections when there was dB issues, but don't know if he ever read that this surfaced before the dB started to suffer.

I think the default is 8 for file transfers ...
<max_file_xfers>4</max_file_xfers>
<max_file_xfers_per_project>4</max_file_xfers_per_project>
I use 4 for my little 5Mb connection, which does handle 3 or 4 computers at once, but slooowwww if they all hit at once.
I try to get their timing offset then it's fine. I never get errors.
The router might not be able to handle 10ish concurrent from multiple computers.

Ahh gotcha, never really paid attention to the SMI version number there ...
NVIDIA-SMI 384.111 Driver Version: 384.111
These are the latest for Mint 17.3

Some answers ...
- It has been up for 21h now since the PSU replacement with 6 new errors.
- 99% of the time it is just a freeze up, normal screen, nothing logged, no sign of what happened. I think it only rebooted once on it's own.
- LOL, I changed to the Gigabyte board when you said you didn't like the B350, and by the video you sent me I picked the GB K7 with was said to be a good OC board.
- I haven't noted any difference if stability really between 3200/3333. I wish I has a Windows machine with DDR4 to read the RAM, but I don't. I would have to clone my Win8.1 and run it offline, but my backup drive is kind of tied up with my Aunt's Mac backups at the moment.
- I have seen the SIGSEGV errors on Ubuntu 16, 14 and Mint 17. Mint 17 would be the only one that had the newest drivers released this week. The Mint 17 is a new install just turned 4 days old on SSD ... I killed my USB Ubuntu 16/14 kernel files whenever I try to push 3.9G. They can probably be repaired ... but oh well, no biggie. I was thinking it might be something to do with USB sticks, but no.
- I don't think it is NVidia drivers, since it carried on thru 3 different OS's, 2 without the latest updates. My guess would be hardware.

It's worth a try ... a known good 750W PSU, UPS not just surge, 3.7/3333Mhz, 65C w/2x120mm fans on AIO now.
1.75h and still up, will have to see ...
Shaved 4m off CPU tasks from 3.4-3.7Ghz, now @50m
Will return this thread back to its regular programming ...

Don't think it's temp, 60C (I think) w/120 AIO which is only luke warm o/p. 140mm front and back on board just to make sure, backplate is cold.
RAM has been fine for any 2h tests I've done, was going to try it for a day or more and see.
Best I got was 6d with original K4 BIOS @ 3.7/3333 (I think) I need to recheck BIOS1 setting w/K4. I'm on BIOS2 now with the updated K10 BIOS.
It's a new 1200W PSU with ~225 load, but yea I guess it's never been tested yet as known good ...

I just wish I could keep my Ryzen running!!! The damn thing runs from 15m to a few days then crashes. Right now it's on stock 3400/3200Mhz RAM and 20h up. Last boot it was 15 min at the same :((( And it always throws a handful of errors whenever it gets the mood to.
I just wish it was reliably unreliable with different settings so I could figure it out. Getting darn tempted to pull the Gigabyte K7 and put in the cheaper ASUS B350 ROG ... I want to put my 1080s in it, but not too productive if it won't frigging run. The other computer is rock solid stable.

A thought ... it's being run with different user logins which cause a reload/ignore of client_state, etc. Could be it's being run from the wrong user account and not 'All Users'
EDIT: Also might explain why Grant(?) mentioned it was on Lunatics, nope it's not, yes it is ... every time they switched logins ???

Hmmm, I wonder .... About the same time these BLC5 tasks showed up, they updated the splitter code (I think) I wonder if the averaging sstem became broken (frozen) or reset to an arbitrary number by doing so ...

oh, and if you forget to change 0.1 back to 10 when you move from Einstein to Seti, you figure it out quickly as you don't get the full allotment of 100 work units per GPU/CPU.....
... And if you forget to change 4.0+0.01 when changing to Einstein (with RS <> 0) to find E@H doesn't have a 100 task limit ... last time I did that and turned my back for a few minutes and have had IIRC 736 tasks ... way, way over committed!

or simply assign a fixed amount of credit for task type. This is the method the Einstein project uses. I get 3465 credits for EVERY FGRPB1G task whether it takes 600 seconds on a 1070Ti or 1150 seconds on a 970.
Simple and fair, someone press DA to use it on SETI.

A flat credit rate MINUS the percentage of rubbish returned for the last 10,000 tasks ... you run errors, you get penalized ... encouragement to fix your system :)

TBarr, we are looking for Zombies where 1 or more tasks are left running occasionally, not every task remaining running every exit - a completely different topic.

With the decline in RTS, I loaded up with an extra 2500 tasks across my Ubuntu 14/16 and Mint 17 systems with v7.2 and v7.6 clients while watching running tasks and didn't see any hang around for more than a few seconds when shutting down by command line. I only did 1 shutdown on each system via the manager, and the same, no problems found.

The 'other' search still continues ...

Post:
The GPU lockfile might also only be created when the task does its checkpoint ... since GPU tasks are fast, there might not be a lockfile whereas CPU tasks would have one ... but then again, you created a GUI lockfile ... but something to think about.

I just watched a couple of GPU tasks, and the lockfile exists on tasks restarts with v7.2.42 restarts ....different with v8.3?
