Lost lock at the same state but this time:

  • Jenne was troubleshooting the issue by manually running different parts of the code to see where the issue happens
  • Happened TRANSITION_FROM_ETMX and this time happened instantly after running the 5s ramp time swap transition (it has made it past this prior, but still lost lock at the same state).
  • alog 75204 talks about this more.
  • Troubleshooting the issue with Jenne now while we re-lock.
