Within the last day or so, cudaminer has been "hanging" after mining some time. The time between accepts always varies a bit, but now it's 1,2,3, or even 10 minutes. Sometimes it resumes sometimes it doesn't Not getting any invalids, but there does seem to be some sort of error?

I'm running a 750ti factory OC + a little more.  Reducing it to stock clock doesn't seem to fix the issue.

6 minutes later it's trucking along just fine, still slower, but no errors. Runs for a minute.. same thing again for a few minutes.
