ulimit -n was 1024, so I am assuming that is likely the problem. So if I understand your reply correctly, I can do a 'ulimit -n 8192' to increase the value, but that is only for the session?
Since I have the program starting at bootup what you are saying is I need to edit these files and reboot, Then ulimit -n should show whatever I set it to below?
FD_SETSIZE defined in: /usr/include/linux/posix_types.h /usr/include/bits/typesizes.h
#define __FD_SETSIZE 8192
Do I have that right? thx

I have always used ulimit -HSn 8192 in the startup of the program. for example, I used it in /etc/rc.d/init.d/squid like so:
<SNIP> start() { ulimit -HSn 8192 echo 8192 > /proc/sys/fs/file-max echo 1024 32768 > /proc/sys/net/ipv4/ip_local_port_range echo 4096 > /proc/sys/net/ipv4/tcp_max_syn_backlog
for adir in $CACHE_SWAP; do if [ ! -d $adir/00 ]; then echo -n "init_cache_dir $adir... " $SQUID -z -F -D 2>/dev/null </SNIP>
Also, You might have to re-compile the program so that it can use these settings. I have to re-compile squid with these values entered or it defaults to 1024.

Put ulimit -n 8192 in the startup script. If you mess with those include files you will have to recompile your program and possibly its dependencies. So try the easy way first ;) modifying include should be considered a last resort.
