When I arrived from work, the SMP2 console was stuck at 11:20:04.
Sinse it looked like it was stuck for the past 9.5 hours, I then stopeed it with Ctrl-C.

I then started the client again, and it gave me a MISSING_WORK_FILES error.
While I was copying the log to post it here, I noticed a whole bunch of stuff after 11:20:04 that was not on the screen.

Two other WUs (one GPU and one Classic) on the same system are processing normally.

The system is a Core i7-980x with 12GB (OCed to 3.9GHZ) running Windows 7 Ultimate (french)

The Microsoft text window can be suspended in a way that prevents the application (FAH, in this case) from updating it. I don't remember the exact way to do it intentionally, but it sounds like what happened here. FAH continued to run and continued to send messages to the console but you didn't see them.

Posted: **Mon Apr 19, 2010 9:58 pm**

Bruce,

I dont think so. If it had continued to run, the WU would have complete at around 15:00.

I checked the processes before stopping it and the "FahCore_a3.exe *32" process was at 0%.
And, the temps where consistent with this.
Wheter it was at 13% or 29%, it did freeze.

Posted: **Mon Apr 19, 2010 10:25 pm**

Maybe . . . maybe not.

Assuming that my guess is correct, FAH would have continued to write console data to the console window until the buffer filled up. I have no knowledge of Windows internals, but it seems logical to assume that the messages between 13% and 29% did, in fact fill up that buffer and FAH could no longer write to the screen, at which point it Windows would have suspended it until the buffer could be cleared.

This might be a way to recreate the issue. Rt-Click on the task bar at the top of the console output and select EDIT+Mark. The title will change to include the word "Mark" Leave it in that condition long enough for one or two messages about % Complete to appear. (I suspect they won't appear.) Now go back to that screen and press Enter, and the messages should appear. If you're really brave,

leave it for much longer and see if FAH is eventually suspended but can be "fixed" it by hitting Enter and letting the messages appear on the screen.

Permit me again to respecfully discount your (helpfull) suggestion.
I did what you suggested and waited 7 minutes (enough for 2% of processing).
When I hit "Enter" the line appeared all at once with their own times, not bunched up together at the same time.
Also note that the input not only stopped on the console but also in the log file.
Thanks

Respect is appreciated, but not necessary.

OK, but we don't have a one-to-one comparison. If, instead of pressing Enter, you had done a CTRL-c (or a shutdown), you would have never seen the screen update but (probably) the messages would have been written to the log file, producing the same sort of results that you reported earlier. The only thing you did NOT confirm was whether Windows would have suspended FAH eventually leaving you with two options (1) Press Enter and allow processing to resume or (2) kill FAH at what might have been an inopportune time. All we know for sure is that if your original problem was more or less like the one we're playing with, you picked 2 without knowing about 1.

Well, I have more to report.
I just completed the WU I got after restarting my client (I should get 3744 points, translating to 19798PPD, not bad

)
The next WU I got was the same I had trouble with this morming : Project: 6069 (Run 0, Clone 1, Gen 0).
We will see how it does. For sure I wont go to bed until it gets to 30%.

Posted: **Tue Apr 20, 2010 2:55 am**

It's now way past my bed time and the console shows 31%

Whether the problem is like what Bruce is thinking or something else, I probably was a one time glich, they happen

Thank you and good night
