System Load Calculations > Error: Apache terminated unexpectedly

[Eleftherios_V]

Hello,

I am currently modelling an office building that has a burn-in room that is 220 m2 and has a room load of 283kW (thats about 1320W/m2).
Whener I run a PRM System load calculation, the proposed building simulation stops and it gives the error: "> Error: Apache terminated unexpectedly".
I tried to see if I reduced the load to 50kW and the simulation ran, which leaves me to presume that the room load is too big for the system to calculate (?).
The burn-in room is using a evaporative cooler only to supply 20C temp.
Does anyone know how I can resolve this?

Thank you,
Terry
