Hi, when I get an error like this in EnergyPlus it usually has very little to do with that surface or that zone. Usually it is a problem elsewhere. I would check the errors you have above and correct as many of those as possible. Also make sure your air flow rates add up and are reasonable. Check your sizing objects, especially zone and system sizing. Finally check the sizes and efficiency you have put on your equipment that sometimes also causes this error.
The last time I got this error (last week) it was because I had incorrectly sizes my chilled ceilings water flow rate. The time before (the week before) my air flow rates where not adding up in my AHU objects. I have been modelling with EnergyPlus for ages too!
