While trying to re-lock, I ran into the same issues that Ryan C and Sheila noted in their alog 77574 (most recent lock) where a glitch in the state ENGAGE_DRMI_ASC to the state TRANSITION_DRMI_TO_3F thought to be BS ST2 causes a lockloss - elevated primary microseism probably makes us more susceptible.

As done in the last Lock Acquisition (survey), staying at ENGAGE_DRMI_ASC until ASC converges (such that lockloss chance from the glitch can be minimized) worked to overcome the glitch, which had a markedly smaller effect.

Once we get to NLN, I will investigate this as noted in Sheila's comment (alog 77575). Additionally, alog 77573 talks briefly about this issue and lists where the glitch was seen. While this happens, here are some more trends of the glitch being seen in multiple BS channels (again, and again and again). Will plan to post another alog summarizing any interesting findings.
