The DR dust monitor counts did not look correct, its was only reading zero for over 2 weeks, I went out and power cycled it and made some counts which I was not able to see on epics. I then tried to restart the IOC, and it struggled to come back. After a little over 5 minutes it did come back and started showing counts again.

The DR is having network issues again, ~an hour after the restart. I'll try swapping this one with one of our 2 pumpless spares.

Swapped the dust monitor and now it won't come back and the IOC can't connect to/see the DM.
