The above is normal / expected behavior.... it is just the condor_startd 
telling the condor_starter to go away.

Couple thoughts:

Are the leaked dir_xxx subdirectories empty? I.e. they do not even 
contain a ".job.ad" file?  In the one time I could reproduce the problem 
on my machine, the subdirectory was indeed empty - in other words, 
HTCondor successfully removed all the files but had an error removing 
the (now empty) subdirectory.   If the leaked directories are also empty 
for you, that would be an easy way to identify which ones you can 
remove... if the subdirectory is older than a few seconds and is empty, 
you could remove it.

Are you using a real-time virus scanner like Windows Security 
Essentials, Windows Defender, etc?  You could try adding 
C:\condor\execute folder to the list of folder excluded from being 
scanned.  In another thread TJ guessed that HTCondor was unable to 
remove the (empty) subdirectory because a virus scanner had it 
temporarily open.
