dbus.pid

On 2011.11 64bit install I get this error message on shutdown/reboot;

Failed to start message bus : The pid file "/var/run/dbus/dbus.pid" exists, if the message bus is not running, remove this file

This file does not exist on my system.

Anyone know a fix?

Re: dbus.pid

it may be a bug in the error message... on my 2011.11 64bit install the dbus PID is at /var/run/dbus.pid

$ cat /var/run/dbus.pid 
794

$ ps -ef|grep 794
dbus       794     1  0 07:48 ?        00:00:00 /usr/bin/dbus-daemon --system

Can you do this?

$ sudo find /var/run -name dbus.pid -exec ls -l {} \;

---

Welly, welly, welly, welly, welly, welly, well. To what do I owe the extreme pleasure of this surprising visit?

Re: dbus.pid

OK I did this but I still have the errror message on shutdown/reboot.

sudo find /var/run -name dbus.pid -exec ls -l {} \;
-rw-r--r-- 1 root root 4 Nov  6 15:21 /var/run/dbus.pid

[root@archbang neil]# rm /var/run/dbus.pid

but the 'dbus.pid' is recreated upon reboot...

Re: dbus.pid

Getting the exact same error on shutdown here

Run below command in terminal

grep ^DAEMONS /etc/rc.conf

Look at output of command.......
is hal before dbus? If hal is started before dbus you will get this error, as hal also starts dbus.
Open your /etc/rc.conf file and make sure dbus is started before hal. Some people just comment out dbus
all together as hal will start dbus.
EXAMPLE:
[root@MS-7005-archbang ~]# grep ^DAEMONS /etc/rc.conf
DAEMONS=(dbus hal guarddog syslog-ng @wicd @alsa cupsd lp anacrond tor privoxy webwasher timidity++ sandfox)

Re: dbus.pid

I don't use hal at all, and have dbus set to start first: DAEMONS=(dbus acpid @wicd @laptop-mode @ntp @crond @syslog-ng @cupsd)

Looking at your log files, there is no hint as to anything else related to this error?
Do you have:

if which dbus-launch >/dev/null && test -z "$DBUS_SESSION_BUS_ADDRESS"; then
    eval "$(dbus-launch --sh-syntax --exit-with-session)"
fi 

Before:

exec ck-launch-session dbus-launch openbox-session 

In your ~/.xinitrc file?

Re: dbus.pid

Apologies, I should have put more details in my first post. I'm running arch with LXDM (via inittab) and XFCE, not using a xinitrc file. I only seem to see the message during shutdown, and not anywhere else that I'm aware of. Luckily it doesn't seem to be harming anything, the system continues to reboot fine. I was more curious what it was and if it had potential to cause issues.
