[c-nsp] SSH login hangs still third session

[Bill Buhlman]

Hi,
I'm running 12.2(33)SRA6 on a 7609-Sup720-3b. Its been up for about a year aand a half. When 
I first deployed it, I was able to login with ssh first try with Putty. About 4 months later 
after I put in username and password, the session hangs until I get "protocol error: 
expected type 50 got -1" (with putty. no error code with Teraterm) At that time if I opened 
another session and put in username and password while the other session was hung I was able 
to login fine. Now, on the first TWO sessions it hangs and the third session I am able to 
login. I've tried different versions of putty and teraterm but doesn't seem to be client 
related. I've regenerated the RSA key twice and I've got an open case with Cisco but no 
resolution so far.
Anyone seen this?
Thanks,
Bill
