DBB causing IMC to lose lock

It's been a suspicion that, lately, switching DBB shutters has been causing IMC to lose lock. Perhaps this action is causing just enough noise to perturb the injection locking? Until further investigation is done, scans will be taken at times when the mode cleaner can be down for a period of time such as maintenance days.
