Hoping to take advantage of the windy night without interferometry I tried to start taking some long-needed acceptance transfer functions on the ITMs. However, I immediately discovered that the IOP outputs from the suspensions were zeroed out. Signals apparently dropped out at for all SUS on h1susb123, i.e. H1SUSITMX, H1SUSBS, and H1SUSITMY at the same time, roughly Dec 12 2014 02:52 UTC (Dec 11 2014 18:52:00 PST, GPS 1102387936 -- about when Sheila noticed that the ITM pitch motions were ~10 [urad] and started to blame the changes to SEI systems), see attached. 

I checked everything I'd checked last time there were loose wires in the software  (see LHO aLOG 13329), but they didn't report any problems:
(1) All SUS watchdogs are green (2014-12-11_H1SUSITMY_Overview.png)
(2) All IOP Software Watchdogs are green (2014-12-11_SWWD_Status.png)
(3) dmesg of h1susb123 doesn't report any badness (2014-12-11_h1susb123_dmesg.txt)
(4) proc status seems happy (2014-12-11_h1susb123_procstatus.txt)

I've called Dave and left a message. I'm going to do the same sledge hammer solution we did last time and kill all USER front end processes, restart the IOP model, and restart the USER models.

I hate this -- we really need a way to reset this WD DACKILL look alive WITHOUT having to take down the entire front end...
