Problem(s) Encountered:

Having trouble with the TCS.  Restarted TCS but dome slit won’t open.  TCS RA is off by 12 minutes of time in RA while telescope is at zenith.  Owl can't get telescope coordinates.  Seem like TCS might have to be power cycled on site.

Another symptom is that both ds9 displays had disappeared sometime during the day

Solution:

Came in this morning and found the telescope itself functioning as expected.  The dome however would not open.  With the weirdness reported by Jules last night, I just brought down and cycled everything (TCS, McGraw, 13tcs linux box, mdm13ws1).  Brought everything back online and tested all telescope/dome functions successfully.
