Ops reported that rfTrimUp/Down script was throwing a socket error because it was unable to turn off

"Unable to suspend AutoChris: <C++ Sockets>: Server is unavailable"

Although it was running, I restarted the rfReset (AKA AutoChris). daemon.

Ops tried again, and the error was thrown - however, the script proceeded to trim.

2L03-7 KRRP Trip at 1152 today

15 hours 23 minutes ago
Log Number: 4476591Logbook(s): Entry Makers: kernsBody: 

Monitored KRRP drop at 1152 and after Mike McCaughan lowered gradient from 18.5Mv/m with 138kW to 9.6Mv/m where KRRP spikes above 250kW and faults. KRRP spiked to 200kW several times today at even lower gradients and pretty sure this corresponds to Cavity de-tuning and CRFP changes during the changes. Running well at 12 Mv/m with ~100 mw KRRP and will stay at that gradient until the rest of the circulators can be monitored as well. Circulator load change outs require no beam and opening the waveguide so this ain't happing until a maintenance day !!!!
