Unable to send key to keyserver

[Newsmail]

I am trying to send my public key to a keyserver using this command, and here 
is the error message that was returned.

gpg --keyserver www.keyserver.net --send-keys 0x6038EB02
gpg: Warning: using insecure memory!
gpg: error sending to `www.keyserver.net': eof

I have also tried replacing the 0x6038EB02 with the name I used in generating 
the key which is John Pitz.  What am I doing wrong?  Please cc
