453204:47-04:5000:03In TCS GUI I was unable to deploy or retract cameras and mirrors. Received the following error message: DeployCWFSMirror caught an exception: Timeout waiting for message ID 5 ACK, spent 5.000000 seconds. Receiver for tcsGuiPfipAsyncCommandSender is likely offline. 2016-05-28T04:35:38.943 DEBUG [tracker_driver.cpp :t_for_final_response: 289] - wait_for_final_response( who=SET_TRAJ, what=OK, idx=49719 ) waiting for command index 49719 Tried operating the cameras and they worked fine. Restarted all servers and the gui and everything worked fine.

453404:40-04:4200:02Upon restarting all servers and starting TCS GUI, received many red forced status even messages in the Command Status window, and the cameras were nonfunctional. Shut down and restarted everything again and it worked.
453506:28-06:3100:03On fresh restart of everything pas is nonfunctional-- PAS light is black at top of TCS GUI. Had to shut everything down and restart again, and afterward the PAS light was green.
