We had at least one lockloss tonight when a violin mode damping filter was reset without having the gain be 0.   Looking at the gaurdian logs, there were both ezca connection errors and same state redirects, although the ezca connection error seems to be the culprit here. 

The log is attached, the reason we lost lock is that the filter states for ITMX_MODE7 were reset in the main state (with the bandpass filter momentarily turned off, which is fine if it happens only once when the gain is set to zero) (lines 47-52).  Then the gain is ramped on line 76.  On line 181 there is an ezca connection error, this is the kind of error we have been having frequently the last few months, bugzilla 1122.

The main state then repeats but isn't idempotent which unlocks the IFO. 

Craig edited the code so that the bandpass filters are no longer momentarily turned off, so this wouldn't be as bad if it happens again.
