Phoenix Miner Crashes when changing config

If I switch config on a running phoenix miner it crashes, then reboots. Runs fine (for 24+ hours) afterwords. Problem started with 5.1c

Sometimes I’ll get an error like this but never the same GPU.
GPU2 CUDA error in : unspecified launch failure (719)

Othertimes it’ll give an error like ‘All CUDA devices busy.’ I tried running ‘stop miner’ before changing the flightsheet but same problem.

recent versions og PhoenixMiner v5.1b/5.1c it’s beta version and may contains bugs
You can select in miner settings previous version which works fine on your hardware

Yup. I know.
