I talked to Sheila this morning about turning on the ETMX glitch limiters from this alog, so I've edited ISC_LOCK to turn this back on. This will cause SDF diffs on ETMX when we get to NLN, but otherwise shouldn't interfere with locking. If it's necessary to turn this off, just comment out lines 5462-5464:

            log('turning on esd limits to reduce ETMX glitches')
            for limits in ['UL','UR','LL','LR']:
                ezca.get_LIGOFilter('SUS-ETMX_L3_ESD_%s'%limits).switch_on('LIMIT')

Still unclear if this is helping, but we turned it off ~Feb 12 after running it for almost 2 weeks.
