iochacp2 was rebooted. Because it is an unknown outlet on hareboot4, I had to reboot almost every outlet on hareboot4.
The outlets I know (do not reboot these unless you know what you're doing!) are:
outlet 3: electron detector motion outlet 4: ETROC (electron crate) outlet 6: ROC 6 (photon FADC crate)
I rebooted all of the others, and one of these is iochacp2. Hopefully there will be an update later on which outlet is actually the right one...
