Problem solved.
Sorry for the noise.
It was a human error on the config.

On the CISCO ACS web interface, you go to the properties of the Switch that is having the intermitence, then re-set the password field.

This happened because the IE auto-filled the field password with a catched value that was not the correct one, I didn't see the error because the password field does not show the actual characters, so I had to re-enter the correct password, and that solved the issue.
