I think am getting more errors on BRP5.

Typically the tasks end with

... Error during CUDA device->host time series length transfer (error: 700)

Looking at the tasks that error, I see that almost always, one or more wing-men have also errored out.

for example

http://einsteinathome.org/workunit/167994884

Is this just co-incidence or is it perhaps a consequence of longer tasks?

Looking at my Pending tasks, which have not errored, it seems less frequent that wing-men error out,

although here

http://einsteinathome.org/workunit/168183349

is an exception.

Does BRP5 generate more errors than BRP4?

On reflection, I changed the nVidia drivers around the same time as BRP5 started to 319.17 which meant I changed from Cuda 5.0 to 5.5.

I will reverse back to 319.32 (latest Cuda 5.0 update) that and see if that improves things.

I will need a few days to see if that has made a difference.

Thanks - I seem to have found

Thanks - I seem to have found at least one common cause for my problem, and i can eventually force it to error a task.

I just noticed the errors seemed to be occurring at similar times, and only on the GPU which was running a monitor. (I run two gtx460s)

If i logout / switch user a few times, eventually - one or two tasks will error.

I guess longer tasks mean that more tasks (as a percentage) will get caught by this.

I´m open to any ideas at this point, but i´m thinking i need to try to find a way to stop X resetting the display.
