I've been using lighttpd pretty successfully on a VPS for several years, but I've hit a snag since upgrading from Ubuntu 14.04 to 16.04.1 on September 30th. (My lighttpd is now 1.4.35.) Twice, upon trying to visit my website, I've found lighttpd not running even though the server itself is still up. lighttpd runs fine once I start it up again. For the second incident, all I have in my lighttpd error logs is:

breakage.log
is empty.
Any hints on how I can figure out what's killing the process? PID 1 is systemd, but PID 7365 is dead by now, and I don't know what it was.
