How many lines are there in the file, and what is the length of the longest line? Emacs will not stop showing line numbers until it actually displays for the first time a line that is wider that line-number-display-limit-width columns. So if the number of lines there is less that line-number-display-limit, but one of the lines is very wide, and that wide line is not at the first portion of the file that Emacs displayed when you visit the file, then you could have line numbers initially, but they will be turned off whenever the wide line comes into the view.
