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.
