1. The gas inlet valve toggle falls down periodically
2. The lights  for the gas flows and pressure went off. When the power strip was checked, they went back on. 
3. The flow for SF6/CFHF3 showed a red deviation light periodically, messing with the displayed flow number. Even with this gas turned off, there was still sudden jumps in gas pressure displayed.
