Hmm... I checked the release notes at www.linux.org.uk, and it was the
2.2.12 kernel that had the update:

File Handles 
     The kernel now supports large numbers of file handles per process.
     The default remains unchanged but can be raised by processes. 

You might check if the compile options for linux are causing it to set the
lower limit... Also make sure the #define MAXCONNECTIONS is greater than
1024... I *think* it tries to do a ulimit on file desc. to that number,
cuz on older versions of linux it generated a runtime error if it was too
high, but you might wanna double check that, in case something different
needs to be done to raise the limit.

--Kevin, who wonders why anyone would run a server on a 2.3.x (development
series) kernel... why not wait for 2.4.1?
