Stuck BRP4?

A week ago, or so, I saw a BRP4 that had run 8 hours and resulted in no percent done. I aborted it, and the rest worked fine.

Today I have one stuck at about 66.5% done going on 6 hours. My gpu is running hotter than idle, but not full temperature. The tasks normally take 40-45 minutes.

I see this in my logs for the running task:

I suspended this one, and the next task appears to be working as normal.

Stuck BRP4?

Your GTX 650 could be OC'd a bit too much and it could be the temp. also.

I have a GeForce GTX 650 Ti (2047MB) myself and did have to mess around with the clock and voltage settings to get it to run it's best and had them freeze once in a while when I first started running it here.

What does your GPU-Z say?

Here is an example of mine (I am on this host right now)

Stock GPU. I did also get two

Stock GPU. I did also get two errors this morning, but I woke up to find the computer off, so no idea what happened there. Temperature is actually down a bit from normal (CPU temp is up as the house temp comes up, so the case fans are running faster). I had plenty of valid results running as high as 65C

Running a live task:
Clock 1058.2 mhz
Mem. 2499.4 mhz
Shader 2116.5 mhz
Temp. 56C
Fan Speed 24%
Mem Used 438MB
GPU load 85%
Controller load: 55%
VEL: 0
VDDC 1.1120V

So, I resumed the task to check the actual gpu load and it reset the time to 28min and began counting up again on the % done. I guess the real test will be if it validates. Edit: uploaded and validated.

I have a CPU version of one

I have a CPU version of one of these on my 64 bit Linux computer.
It has run for 20 hours 30 minutes, is at 43.802% and has been for a very long time, no progress is happening, it also has no Time to Completion just a blank.

I suspended and resumed the work unit and am waiting to see if it starts up normally again or continues with no progress.

I have experienced something similar on the GPU side - seems to be taking a nap but the wu will eventually complete. My workaround has been to suspend all Boinc tasks, reboot the computer and resume Boinc. Seems to clear out the cobwebs and once in-progress tasks are completed normal task completion times return.

I ended up restarting BOINC

I ended up restarting BOINC Manager and Client.
This made me lose 13 hours on the Einstein work unit (dropped from 20 hours to 7) and 5 hours disappeared from the Albert work unit (from 17 hours to 12).
But the time to completion has been restored and the Einstein work unit at least is progressing normally now.

(I also had a Wildlife@home work unit do something similar which also reset with the restart).

Seems that for many hours these work units were actually doing nothing at all.
Bit of a mystery that.

Other projects have been working fine during this same time.

SOMETIMES a simple suspend and then after a 5 count a resume will restart the unit without a full shutdown and restart of Boinc. I am NOT a programmer but this happens rarely but often enough to make me think it could be a background program running that grabs the resources and then doesn't give them back when it is done. This is common in Windows, not releasing the resources, but the problem happens in Linux too and I thought it was better then that.
