I am getting jquery error

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

Script: http://localhost/idea/theme/de…es/jquery/jquery-1.11.1.min.js:2

I am getting this error when I am trying to load display page.
what should I do to get rid of this error?
