OK. Keep an eye on things when you can. With things running a bit more smoothly, I am currently starting a rewrite of the problem pulsefinds once and for all (i.e. VLAR & display lag related). That's going to take time & care, but at least the experience garnered so far should see things get a lot better from this point, in terms of both reliability & performance.

For those following this thread & using the x39c diagnostic, please update to the attached build with some added diagnostic info printed on errors.
[Removed old build]

Got it Jason, now if only SETI would cooperate. I've just started getting the can't connect to server message when trying to upload. I hope it's Hurricane Electric working on the problem. But anyway, another day of no problems, seems dropping back to two tasks has cured my problem.
Okay, finally got some reports through. Here's the link to one of the validated WUs I finished on x39d just in case you wanted to look at it. http://setiathome.berkeley.edu/result.php?resultid=1967582734

In the meantime, I've noticed Cuda 'freaking out' here on the 480 with newer builds ... but only when FireFox is Running... weird. No Errors, but certainly seems to stick in some funky lag-mode.
I'm trying your solution of stepping down from 3 to 2 tasks. If that helps I'd take it as an indication that the loading presented by the newer builds is indeed substantially higher overall. I may have to retest which number of tasks gives the most throughput here, as 2 task loading seems to be >95% now. I wasn't expecting that to change until later when I get a bit more optimisation in... Will see.
[Edit:] Stepping down to 2 seems to have helped here too, will keep an eye on it for a while.

If you mean it seems to stick for a little while, I'm seeing that too. Mine seems to stick at around 96 to 98% and hold for somewhere around 30 seconds to a minute then pick up and run on to completion. I haven't tried it with firefox closed and I don't know exactly how often this happens.
