ETMX SC brief dropout

Not sure how common this is, but the ISI_ETMX_ST1_SC Guardian briefly went into fault and then returned to its nominal state

This is from the BRS DAMPCTRLMON channel dropping to 0. When this drops to 0, it will often mena that the code has crashes, but the trend shows frequent drops to 0. The ISI_ETMX_ST1_SC node changed states to remove the BRS sensor corrected signal from the SC path because it thought that there was a problem with the  BRS.

SEI: What is going on with this DAMPCTRLMON channel, and will I need to add a timer to the sensor correction nodes to check that this channel stays at 0 before transitioning?
