Why Cisco 6509 Limited To Only 2 Telnet Sessions

I have 2 Cisco 6509's with line vty 0 -4 and 5 - 15 configured.  But anytime there are 2 users logged on via telnet, additional sessions are not accepted.  I am unable to even telnet to other devices from  these switches.  When I run the "sho users, it only shows 2.  

se config:

line con 0
 exec-timeout 0 0
 password xxx
 login
line vty 0 4
 exec-timeout 60 0
 password xxx
 login
 transport input lat pad udptn telnet rlogin ssh
line vty 5 15
 password xxx
 login
 transport input lat pad udptn telnet rlogin ssh
!
exception core-file

When you try to telnet into these switches (the 6509's), it either hangs on Trying to open, or it says refused or blan screen.

Everything else seems to work fine.

Thanks

I can do "show line", who etc and it would show 2 connections .  Once that occurs, thr router cannot telnet to other routers or be telneted to...connections in or out are refused.

No, this is the core switch of the entire network.  Everything seem to be working but just the telnet having problems.

Right now I cannot even get in.  I am waiting for Cisco to work with me on that but any hekp from you in the mean time will be helpful.

When I am able to get on the switch, and run the "show line" command, there are no more than 2 vty in use.  

And I am runn ing native IOS.  Both swithes have 10 G modules with Sup 720 sup's.

IOS ver. 12.2(33)SXH3
