Two days ago I tried to upgrade miner to 11.7, hashrate slightly rose by and i've been happy, but after some time always' i've got an error "server: accept failed with error: 10004". I read a lot of messages related to this error and tried to change various settings following the tips in this topic, but finally I've tired to see this cr@p and rolled back the 10.2 (on this version the rig works stably). Damn, it's sad story, because new version has a more advanced configuration options. I cherish the hope that in next releases it could be fixed.
