One issue that I've been getting since earlier versions is that, while mining on a pool with multi-algo support (MO), sometimes the miner will just close without any apparent reason. The command prompt window just closes. When checking the log, nothing abnormal was happening. Sometimes the last line on the log is an algo change, sometimes is submitting a share. Miner just closes. Any idea of what may cause that or what else can I do to test more and provide more feedback?
I was having the same issue without using profit switching, just a single coin. Tracked the problem down to the AMD driver crashing. The only solution I found was to lower the intensity setting by 10-20%. Yes, you get a lower hash rate, but the program doesnt crash either.
