Following up on EJ's alog, I have extended the code to check if the unresponsive filter is under local control by the model. I ran it this afternoon while H1 was in observe, running in 'nice' mode so as to not hammer the frontends with CA requests (delays between requests).

If we disregard locally controlled filters, the number of unresponsive filters is reduced to 3 (see attached). The top one runs on h1lsc, the other two on h1lscaux.

Here is the full list, with locally controlled filters marked with *

Total numer of filtermodules = 13367
num unresponsive 14

h1lsc {'LSC-EXTRA_AI_2': 'FM2  '}

h1lscaux {'LSC-LOCKIN_1_DEMOD_9_I': 'FM1  ',
          'LSC-LOCKIN_1_DEMOD_9_Q': 'FM1  '}
