Mod parameter in server startup line will only load a certain number of mods based on a set number of available character spaces for the parameter.
This is true using "-mod=@mod0;@mod1;@mod2" etc. from the startup line or using -par=nameOfFile.txt or -par=nameOfFile.par as described here: https://community.bistudio.com/wiki/Startup_Parameters_Config_File
Add to the server start-up line:
mod line parameter:
-mod=@mod1;@mod2;@mod3;@mod4;@mod5;@mod6;@mod7;@mod8;@mod9;@mod10
OR
add the -par parameter using either:
-par=nameOfFile.txt
contents of nameOfFile.txt:
-mod=@mod1;@mod2;@mod3;@mod4;@mod5;@mod6;@mod7;@mod8;@mod9;@mod10-par=nameOfFile.par
contents of nameOfFile.par:
class Arg
{
mod=" -mod=@mod0;@mod1;@mod2;@mod3;@mod4;@mod5;@mod6;@mod7;@mod8;@mod9";
};result is server launched with only 7 of 10 mods.

As much as Arma is community orientated toward modifications this should be a high priority. There shouldn't be a limitation on how many mods can be launched with the server.
This is quite annoying, and I think the only solution is to merge mods into the same folder.
