Re: [Starcluster] Paramiko.SSHException

I'd like to add that this problem only seems to be affecting my 32-bit
AMI. My 64-bit ami is working totally fine.

(I've been using both continually for the past 6 weeks with no problem until
today.) I last started up a 32-bit cluster a few days ago.

Thanks -- (and hoping to hear from someone soon, this is kind of an
emergency for me! I depend on starcluster so thoroughly now!)
