Although the error reporting is not detailed enough yet on the production server to provide the channel name and value that caused an error upon attempting to insert it into the MySQL database, it is on the test system. The following channels and values caused errors on the test system: Jul 11 16:59:40 H1:OMC-READOUT_ERR_GAIN: -nan Aug 4 07:54:43 H1:SYS-MOTION_C_PICO_F_MOTOR_1_NAME: 'xF3x01' Aug 8 12:25:47 H1:OMC-READOUT_ERR_GAIN: -nan
This is nice, it gives us a sense of how often the calculations for the handoff to DC readout fail. Answer: about once a month.
We should have the OMC guardian check that the calculated value for OMC_READOUT_ERR gain is sensible before writing it to the epics channel.
