While editing the ~/.emacs file in emacs, the machine rebooted (kernel
panic I believe). This left a lock file behind.

The ~/.emacs file is actually a softlink:
.emacs -> /Users/<username>/Dropbox/Documents/Projects/emacs/dotemacs
The fact that it's a softlink may or may not be relevant.

In ~/Dropbox/Documents/Projects/emacs/, there was a file: .#dotemacs

After the reboot, I started emacs, and continued with further edits to
.emacs. Upon saving .emacs, had the following warning:
⛔ Warning (unlock-file): Unlocking file: Invalid
argument, ~/Dropbox/Documents/Projects/emacs/dotemacs, ignored

As per the warning, the save was nonetheless successful.

Invoking file-locked-p directly, I saw the same error, and the following
debug info:
Debugger entered--Lisp error: (file-error "Testing file lock" "Invalid
argument" "~/Dropbox/Documents/Projects/emacs/dotemacs")
  file-locked-p("~/Dropbox/Documents/Projects/emacs/dotemacs")
  eval((file-locked-p "~/Dropbox/Documents/Projects/emacs/dotemacs") t)
  eval-expression((file-locked-p
"~/Dropbox/Documents/Projects/emacs/dotemacs") nil nil 127)
  funcall-interactively(eval-expression (file-locked-p
"~/Dropbox/Documents/Projects/emacs/dotemacs") nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)

After removing the lock file manually, the warning on save goes away:
rm ~/Dropbox/Documents/Projects/emacs/.#dotemacs

Access flags on dotemacs file are as follows:
-rw-r--r--@  1 dgreatwood  staff  133806 May 15 16:01 dotemacs
lrwxr-xr-x  1 dgreatwood  staff  59 Dec  6  2015 .emacs -> ...

Thanks.
