it is a standard default on most OS's that are released, really has nothing to do with a hosting company setting limitations, and has nothing to do with boonex. this would be a good sticky note for a migrations thread though.
there are other limitations that are on most all *nix distros, and until you hit that limit, you really dont even realize they are there. these limitations of bottom boundaries are just part of the programming of the OS.
MD is correct, most hosts do not alter the server see more settings, that is one of the reasons that boonex recommends using a VPS (minimum) or a Dedicated Server. There are hosts who will run an optimized shared environment for hosting dolphin (no names named), and those configurations are outside the standardized setup that you would get from an ISO image.
Summary:
most everything that is default and mass released has limitations, there are upper and lower boundaries that are considered by these developers in all cases, and how they arrive at their calcs are most likely proprietary to that OS build. If these boundary limitations are of a concern, then by all means grab yourself a dedicated server, then you can fight the fight, and when the whole server comes crashing down, you will have a better understanding of what is going on. (maybe).
