No, this is not OS dependent at all. slapd allocates its own Connection array based on the number of available descriptors. There's nothing unusual going on here, though 500K+ descriptors seems a bit excessive. Unless you have a server listening on multiple network interfaces, the most connections you're likely to get is 32768 or shy of 65536, depending on OS. You should really think about what you're trying to accomplish and what the realistic constraints actually are.
On deployments with multi-million users (of which we have), it is not unreasonable that between slapd/imap/pop/mysql etc for there to be a need for a high number of file descriptors in use for the zimbra user. However, I think it may be reasonable to break slapd out into its own user, so it can use a reduced set of file descriptors.
