I wonder if the problem could be due to recentf if the option
`recentf-auto-cleanup' is enabled to cleanup the recentf list each
time Emacs has been idle during N seconds?

Because in this case, the function `recentf-cleanup' is called every N
seconds, in turn calling `recentf-keep-p' to checks if a file name
should be kept in the recentf list based on the `recentf-keep' option,
whose default value is the predicate `recentf-keep-default-predicate'
that uses `file-remote-p':

(defun recentf-keep-default-predicate (file)
   "Return non-nil if FILE should be kept in the recent list.
It handles the case of remote files as well."
   (cond
    ((file-remote-p file nil t) (recentf-access-file file))
    ((file-remote-p file))
    ((file-readable-p file))))
