[Bug 1273258] Re: Hundreds of dbus-daemon processes

Hi Scott,
I do also work for Salesforce.
It would be an interesting indication if this symptom was *only*
experienced at Salesforce.
It would tell about interactions with specific tools we use.
What could it be?
- puppet
- avahi
...
In fact below is the list of binaries having a pid on my box now.
Now, when I killed my running dbus-daemon processes last time, I got a
crash of compiz:
/usr/bin/compiz
SIGSEGV in_IceTransClose
DistroCodeName: precise
https://bugs.launchpad.net/bugs/969078
with a popup:
Apport
'precise' is no longer under development
Maybe this is an indication?
Thanks
Marc

Title:
Hundreds of dbus-daemon processes
Status in “dbus” package in Ubuntu:
New
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

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.
