I just had this on my 1 week old new laptop running Ubuntu 14.04.1. I
ran "strace -s 128 -p <PID>" where PID was the pid of initctl, and the
output looked like this (small excerpt only included):

poll([{fd=3, events=POLLIN}], 1, 4198964686) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964682) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964680) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964677) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964675) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964673) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964670) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964668) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964665) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964663) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964660) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964657) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964654) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964650) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964647) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964645) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964643) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964640) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964638) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964636) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964633) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964631) = 1 ([{fd=3, revents=POLLIN}])
poll([{fd=3, events=POLLIN}], 1, 4198964628) = 1 ([{fd=3, revents=POLLIN}])

I looked in /proc/PID/fd, and it looked like this:

dr-x------ 2 root root  0 okt.  21 07:50 .
dr-xr-xr-x 9 root root  0 okt.  20 10:58 ..
lrwx------ 1 root root 64 okt.  21 07:50 0 -> /dev/null
lrwx------ 1 root root 64 okt.  21 07:50 1 -> /dev/pts/14
lrwx------ 1 root root 64 okt.  21 07:50 2 -> /dev/pts/14
lrwx------ 1 root root 64 okt.  21 07:50 3 -> socket:[10190]


I also ran "lsof | grep 10190", and the output looked like this:

initctl   1268             root    3u     unix 0xffff8800d719d400
0t0      10190 socket

Not sure any of this helps, but that's what it is showing while using
100% cpu. My laptop is a Toshiba Portege Z30 with a dual core i7-4510U
CPU. I'm running arch amd64.

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
