I have been enjoying a very low error rate on ATLAS 1.44 until this morning, when I got a series of 9 errors, with 5 of them (thus far) being completed OK on other machines. And the errors occurred in the first 5 or 6 minutes of the start of a WU, so it looks like a basic incompatibility of some sort.
The only difference I can see from earlier is that I started Folding on my two GTX 960 a couple of weeks ago, but also got a Folding error this morning, which is a bit unusual also. So I removed Folding and started using BOINC projects only on the GPUs (POEM at the moment), and no early failures thus far.
So there may be an interaction between Folding and BOINC/ATLAS, if it is not just a coincidence. It may depend on the particular Folding work unit that is running; some are more demanding than others.
