Is there any information available on this known problem? Historically, we've shipped OpenLDAP built with tcp_wrapper support, but I've been wanting to change that, some motivation would make it easier.

TCP wrappers uses stdio. stdio has a limitation on the number of open files that it supports due to the layout of the FILE structure that's smaller than the limit the system supports. This is an ABI problem on several platforms (Linux isn't the only one that had this problem) which is generally fixed as part of the 64-bit architecture change.
