Poll and Select not scaling

[Micah Gorrell]

If I am asking this in the wrong place I apoligize in advace.  Please let me
know where the correct forum would be.

I have been trying to increase the scalabilty of an email server that has
been ported to Linux.  It was originally written for Netware, and there we
are able to provide over 30,000 connections at any given time.  On Linux
however select stops working after the first 1024 connections.  I have
changed include/linux/fs.h and updated NR_FILE to be 81920.  In test
applications I have been able to create well over 30,000 connections but I
am unable to do either a select or a poll on them.  Does any one know what I
can do to fix this?
