System locks at 24 to 26 hours run time

Running Claymore 11.1 with drivers 16.3.2

Twice now between the 24th and 26th hour of running the rig green screens and stops. Does anyone else have this issue?

I have now placed -r 720 into the config to restart the program every 12 hours
Wasn't sure if maybe this was a log issue

Any input would be appreciated.
