I just had limewire crash while running java_g, so I poked around a bit.
I found this.

whats newfd allocated at?

# ulimit -n
15360 (It's set pretty big because samba likes lots of fds.)
FD_SETSIZE? Not redefined anywhere....
# grep FD_SETSIZE /usr/include/sys/types.h
* FD_SETSIZE may be defined by the user, but the default here should
#ifndef FD_SETSIZE
#define FD_SETSIZE 1024
oops, no wonder it didn't like the 1024th fd. Maybe that MIN should be MAX?
I'm compiling right now, to see how this works.
