Evan, Stefan,

Our late night work was hampered by repeated lock-losses engaging SRC2 loop during the DRMI phase. The few times we made it through that stafe, we lost it in the IFO ASC stage, when the SRCL2 loop gets extra gain.

We tried both a high SRCL offload and low SRCL offload configurations (Gain of 1 and 0.1 respectively in SRM M2 stage.) The high SRCL offload configuration resulted in a 18sec oscillation, growing to a lock-loss.  The low configuration (the default) also broke the loss several times, but we are not sure why.
