Over the past 2 days I've been seeing lots of IMC locklosses right after a main lockloss while ISC_LOCK is in READY. This has been happening 10+ times between relocks. The IMC guardian seems to lock for a split second in its "AQUIRE" state then as soon as it moves on to "BOOST" it loses it. It looks the the MC2 transmision maybe isn't stable, then the BOOST state turns on MC2 lock filters and ramps gains. We also see the bottom stage of MC2 SUS saturate during this. Some are from FSS oscillations but not all.
