Today squeezing did not inject at the "inject squeezing" ISC_LOCK guardian state. First, I saw that the sqz CLF guardian said the pump ISS was down due to multiple failed locking attempts. I noticed that the "SQZ-OPO_REFL_REJECTED" PD was in error, saying "voltage readback saturated". I reduced the gain settings to 20 (dB I assume), and the error message went away. Then, I took the CLF guardian to down and re-requested locked, which removed the guardian error message. That worked, but we still did not make it to "sqz ready ifo". The "SQZ-FC" guardian was failing to find IR over and over. I am not sure if that is because of the updates to the FC mirror offloading (alog 68914). I took the SQZ guardian to "no squeezing" for now.
