Se in my previos post.

Regression logs showed problems with 1.32 and 1.33 . GPU timeouts, and stratum timeouts.

On some of my test rigs the rig was sleeping for 3 minutes almost every hour, loosing 5% poolside hash. For single card rigs not a problem, and might work on some pools. But still a pretty serious bug. We are working on a better fix. The 1.34 windows version still have stratum disconnects but only 5 seconds instead of 180++
