context queue limit.

Hi, 
I was just playing around with context queues, and notice I can't add more then 1021 context's in a queue.
Can someone confirm this for me, just in case it's on system setup related.
I've tested this in Redhat 9, 7.3 and Suse 8.0.
same thing occurs.
I use "icmp_echo_cq.c" as the testing method.

This is the error I get when I try to add 1022 contextes:

libnet_init() failed: libnet_select_device(): ifaddrlist : socket: Too many open files
