Public bug reported:
After upgrading to latest overlay (unfortunately there's about 150
packages to upgrade between the last image and overlay) dbus-monitor
shows dbus/upstart spamming system dbus with NameOwnerChanged signals -
there's no crash files or anything, but the top of top looks like so:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

dbus-monitor shows hundreds of events like so:
signal time=1462098650.817539 sender=:1.0 -> destination=(null destination)

string "ARG2=:1.167"
]
3s of dbus-monitor:
$ time dbus-monitor > dbus.log
^C
real 0m2.719s
Shows 226 signals - so it's just under 100 signals a second:
$ grep -c NameOwnerChanged dbus.log
226
