This morning at about 10:30 UTC I updated to cups-2.1.3-4ubuntu0.3 on my 64bit Xubuntu-16.04 using kernel 4.4.0-92 and it has so far not stopped running.
My /etc/cups/cupsd.conf has the "WebInterface Yes" entry but so far no problems at all, though I had no problems with the cups-2.1.3-4ubuntu0.2 version either to which I upgradede with a comment on January 26th.
