I have committed the fix into the -current branch, svn r198111.
Please give it a try and I plan to MFC the patch into 8.0 release branch
in 3 days.

Thank you for the report.

  This turned out to be a regression bug. A wrong variable is used and
  the incomplete entry was timing out too fast. So the ARP probe =
continues
  indefinitely ...

  I wasn't returning incomplete entries, but now I am ...

  I have a patch for both issues, but I need to clean up the code
  because that wrong variable is used elsewhere in the same module.

  I should be able to commit a permanent fix by tomorrow.
