reversed flow in 108 faces on pressure-outlet 8. temperature limited to 1.000000e+00 in 15 cells on zone 2 in domain 1 temperature limited to 5.000000e+03 in 3 cells on zone 2 in domain 1

1) Reversed flow on pressure outlet means that their is backflow on 108 faces on this boundary. As far as I know the FLUENT by default assumes the area vector direction for a boundary as pointing out of the domain. At a pressure outlet boundary it is aasumed that the flow would normally go out of the domain. However it is perfectly possible that at some parts of the pressure outlet boundary (or even on the entire boundary) the flow reverses and enters the domain. In this case the FLUENT gives this message.

2) The minimum and maximum limits for temperature for your case are set as 1 and 5000 units respectively. During the iterations the tempertaure in some cells is trying to go out of these limits but the FLUENT won't let it go and prints this message. You can change the limits from Solve/Controls/Limits...
