BRS EY restarted

[Jim, Jonathan, Erik]

BRS EY was restarted to try to damp high amplitude oscillations that started around 08:50 PDT.

We shutd down the processes in this order:

Epics

University of Washington process

TwinCAT PLC software

Then we restarted the server and started the same process in reverse order from desktop icons.

The restart did not have any apparent effect on the oscillations.
