Max items means how many items a container will hold.  So if it's set to 5 items and the container has 5 items, it won't respawn loot until it has 4 or less.  (Some mods seem to ignore this setting, as well as some custom maps)  Also remember some modded maps won't respawn.  The current mod maps I know of that will respawn are South Muldraugh, Bedford Falls and New Denver     You need to set this on the Server.Ini file. The time frame doesn't matter, just make sure it's set to 2 o
