ActionDispatch::Cookies:CookieOverflow in controller

I am getting error while accessing rails application, which was working fine earlier,
"raise CookieOverflow if options[:value].bytesize > MAX_COOKIE_SIZE"

Could some one help.

Hey Sai,

Your browser has a maximum size of storage for cookies, so Rails protects you from sending too much data to the browser.

You should probably look at what you're storing in the cookies and change it to save to the database and store the database record ID in the cookie instead.
