How many open buffers do you have?

  M-: (length (buffer-list)) RET

will tell you.  If it's an unusal amount, you can eval

  (dolist (b (buffer-list))
    (message "%S" (buffer-name b))) <=== C-x C-e here!

in order to print all buffers' names to *Messages*.  My guess is you use
some package which creates buffers over buffers without cleaning up.
