Stratum connection interrupted regularly occurs on my box but does not crash sgminer, it resumes normally. If sgminer is crashing you may have setting for one of the cards intensity set too high, try lowering intensity

Update to 14.4 drivers

Intensity doesn't seem to have an effect, tried as low as 13 and it still crashed. The updated drivers I will try though.

difficulty is high. he meant 0.008, lowest difficulty.
Trying this now! Hope it works.
