I am currently running GFN 18 on my GPU (GTX 750Ti) and I noticed that the WU periodically and temporarily just stopped processing. GPU use dropped to near zero and the WU shows no increase in amount done. These coffee breaks last pretty close to 10 minutes in length (often in pairs) but time between coffee breaks is variable. Is this normal, is there something wrong with the geneferocl.exe, or is my computer playing mind games with me?

It doesn't hurt me that much as I am chasing WUProp hours rather than 1st Prime finder. However it does cause the work units that should be processed in a little over an hour to take multiple hours to complete. (As I report immediately/grab only one task at a time, the time between sent and reported is the time that it is sitting on my GPU.) And I think that we all would prefer that I complete as many WU as I can for any given time span.

This behavior was not present in the GFN 15 WU I had been processing previously.

Just a guess, but it seems similar to this (at least for the ~10 min pauses).

Thanks, as the WUs completed I didn't think of looking at the stderr output. Looks like I need to look into the minor OC that I put in place years ago.
