Could not acquire the NetworkManager service as it is already taken

[moose]

Binary package hint: network-manager

To get an ip address I have to
restart the network manager. Once this is done everything works.

This was found in syslog:
Aug 29 14:39:53 strap NetworkManager: <WARN>
nm_dbus_manager_start_service(): Could not acquire the NetworkManager
service as it is already taken.
Aug 29 14:39:53 strap NetworkManager: <info> disconnected by the system
bus.

that just repeats until I restart NetworkManager.

see attached part of syslog showing from broken to working. did this:
sudo invoke-rc.d NetworkManager restart
in between.

this is on intrepid alpha 4 with all updates as of AUG 30, 2008 including 2.6.27-2 kernel.

just updated on 6 sept 2008 which should be alpha 5. rebooted. still the same repeating 2 lines. did the restart and noticed this in the logs.

how many NetworkManager processes are running when you see this message?

is this happening after a clean reboot top?

[moose (snyderra)]

one. clean reboot.
I rebooted then did the following:
snyderra@strap:~$ ps aux | grep NetworkManager

is this a dupe of 261808. I just submitted one and apport says that it was a
dupe. I cannot check because launchpad says that I dont have permission to
view https://bugs.launchpad.net/bugs/261808

I booted up alpha 5 live cd. it does the same thing in live session mode.
installed alpha 5 and it still acts the same but segfaults in a different
location. see below.

i opened bug 261808 up now. Does this still happen in latest intrepid?

[moose (snyderra)]

this happened in a fresh install of alpha 5 plus updates. restarted
the network manager and the crash report tool took over from there and
reported bug 267508. following emails reported that it was a dupe of
bug 261808. so short answer is yes it's still happening. only
difference is that for me networking was not working to start with,
but after restarting network manager it does work.

should this bug be separate or is it related to the original bug report?

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

I get the same error with the latest 2.6.27.11 kernel. When the wireless connection is active on my desktop, i can ping google.com successfully, but will see nm-system-setti[xxx] errors in dmesg. if i try to open up firefox or a new terminal, the circle hourglass appears for a few seconds, then goes away and the terminal or firefox is not opened (as if i didn't try to open it in the first place). continue to see additional nm-system-setti segfault errors in dmesg. same pc works fine with 8.04.

[moose (snyderra)]

sorry new computer with different hardware. cant help.
