Happens on Ubuntu 16.10 (fresh install, Compiz fallback session) after a few
hours of uptime.
htop reports 100% usage of one CPU for the command
/sbin/initctl emit indicator-services-start
which goes on indefinitely. Tracing (with only this initctl process
around) yields similar to #5
$ sudo strace -p `pidof initctl`
poll([{fd=3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}])
[endless repeat]
/var/log/upstart is empty and dmesg/kern.log/syslog don't help.
The random battery drain is annoying (especially during presentations),
and apt purging upstart depends on a little too much for comfort.
Suggestions?

Title:
initctl continuously takes 100% of CPU
Status in upstart package in Ubuntu:
Confirmed
Bug description:
Many programs are fairly slow to start on my computer, despite it
being relatively new (core i5). Suspecting a heavy CPU usage, I
started gnome-system-monitor: all processes were displayed at 0% CPU,
but the overall load was 1.33; 1.33; 1.34.
Using the "top" command, however, revealed the real CPU use, with the
"initctl" process taking 100%CPU, even 1 hour after startup.
I upgraded to roaring ringtail before checking this but the symptoms
were the same with quantal quetzal, so there is a fair chance the
causes were identical.
Regards
