Salvatore,


Sorry i didn't respond.  things have been way crazy.  Unfortunately, i probably won't be able to test because:
   - problem is not reproducible easily sometimes
   - this machine services several hundred systems w/o any upcoming scheduled downtime.

I haven't noticed the problem on any other machines we have, though, so don't have any other candidates for testing.

I may just take the "upgrade to stretch" solution out of this when i have some scheduled downtime.

thanks,
