At 17:40 UTC the ISC_DRMI Guardian had an the following error: "EzcaError: Could not get value from channel: <PV 'H1:LSC-PD_DOF_MTRX_SETTING_5_18', count=1, type=double, access=read/write>, None"

A caget of the channel yielded a value so it seems as though it was just the Guardian that was not seeing it. Reloading the code did not fix the error, and we were already on the phone with Jamie with another Guardian oddity (alog to follow). Jamie suggested that we STOP the node and then set it back to EXEC. This worked!

This has been seen before (example: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=19673) and seems to not be the same channels but from H1:LSC-PD_DOF_MTRX. Jamie and Dave both have their thinking caps on and are trying to solve the problem.
