Have you tried what HaDeS suggested ?
All the maps should load using 512 RAM settings
and with 4 Gb address checked
(or try the old fix,by running S3TC compression)
the map itself whether it loads or not has really nothing to do with your server
a map is just that,a map
Does the map and or mission load for you in FMB ?
If not,then use the settings suggested above from HaDeS
plz just try my map...if it will work fine on your server then i will try to find what's up with my server
ps:
I just looked at the mission file,it is this map the mission is made on>
Northern_Africa_Jir
That map,does not even have an added texture folder
it is just the map folder ,using textures already in the UP 3 Base
So the footprint on that map is very small
Does that map load up for you in just the FMB ?
