Bug report Hog4 os4.0 roadhog dp8k crashing

Using a roadhog with latest release of OS 4.0 the internal dp8 goes offline when recording a cue or pallet. 
pig+open+backspace allows me to restart the internal dp8k. The output blinks and controll is regained. 

using only ‘standard’ fixtures. 

Currently doing a full install and a new show to see if this solves the problem
