I've run into that bug (I think) on lots of sites, including two of my credit card issuers. They set so many cookies, and new ones on every visit, with long expirations, until the cookie header is so large that either the browser or server is cutting it off and you can't pick up the cookies to log in any more. I go wipe out some cookies to fix that too.
