[Diego Machado Dias]

I have the same bug: a number of /usr/bin/dbus-deamon processes which
spawn from "/sbin/init splash".

Title:
  Hundreds of dbus-daemon processes

Status in dbus package in Ubuntu:
  Confirmed

Bug description:
  I find a growing number of root owned dbus-daemon processes.
  Eventually, this results in a 'too many processes' error preventing something to fork, e.g. a login.

  They get created by batches of 4, every 30 minutes on my box.
  My box is a puppet client, so that these 30 minutes are not in a local cron tab.
  The pids are 11 units apart (when the box is otherwise idle).
  The command line is:
  //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session

  ~# ps -fu root | grep dbus-daemon | grep -v grep | tail -8
  root     17509     1  0 11:25 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17520     1  0 11:25 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17531     1  0 11:25 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17542     1  0 11:25 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17972     1  0 11:55 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17983     1  0 11:55 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     17994     1  0 11:55 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session
  root     18005     1  0 11:55 ?        00:00:00 //bin/dbus-daemon --fork --print-pid 4 --print-address 6 --session

  I reported this first to https://bugs.freedesktop.org/show_bug.cgi?id=74114
  and was told to report it to ubuntu instead.
  Here were some additional comments:

  The symptoms you described probably mean that something running as
  root is either running /usr/bin/dbus-launch, or attempting to access a
  D-Bus session via the autolaunch: transport while under a transient
  X11 session, 4 times every 30 minutes.

  If this machine does not intentionally run an X11 GUI or a D-Bus
  session, uninstalling the dbus-x11 package or making /usr/bin/dbus-
  launch non-executable might work around this. Don't do that if you use
  an X11 GUI environment, though.

  Since 1.4.8, dbus autolaunch has only been effective when DISPLAY is
  set and non-empty, so if this is autolaunch, an X11 session must be
  involved somehow.
