[Stephen Cradock (s-cradock)]

This error shows up today (2010-07-10) in maverick with the new kernel (2.6.35.7-generic) [ NOT -pae].

The error report includes

"Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/gtk-2.0/gi/__init__.py", line 27, in <module>
    from gi.repository import GObject

as above.

Running "bootchart" or "sudo bootchart" in a terminal gives:

I haven't used bootchart for some time now, but I did notice similar symptoms with Rhythmbox after updating just now:

To me this looks more like an issue with a recently updated version of Python or one of its modules than anything else.

[Stephen Cradock (s-cradock)]

I have to agree with Akria - in fact, apport-gtk crashes with the same error immediately after the pybootchartgui crash, and then there is a crash in applet.py following that.....

How can we add python2.6 to the packages affected? I've seen it done, but I don't know how....

[Anders Norgaard (anders-norgaard)]

Hi Zachary,

Thanks for uploading your "-maverick-20100710-1.tgz" file.

When I look in it the proc_ps.log ends with a line half written, and proc_stat.log and proc_diststat.log are both empty.

My guess is that the bootchart logger crashed randomly for some reason.

Can you reproduce the error?

Best,
Anders

[Anders Norgaard (anders-norgaard)]

Hi Stephen and Akira,

I think you are seeing crashes related to GObject introspection. Like the one reported here

https://bugs.launchpad.net/bugs/603943

Best,
Anders

[Zachary Scott (zzak-deactivatedaccount)]

@Anders

All I'm doing is booting up to reproduce, I'll attach the dmesg output and the pertaining bootchart.

Is there another log I could use that would detail more about the crash?

Zak

[Hugo Tavares Reis (htr)]

Hi.

I guess its a regression. I just installed an older version of python-gobject and everything is working.

python-gobject_2.21.3-0ubuntu1_amd64.deb

-h

[Jean-Louis Dupond (dupondje)]

Crashing here also, but I doubt its a pybootchart issue, as its not the only Python app that got issues ...

[Anders Norgaard (anders-norgaard)]

@Zachary

Unfortunately I am no expert on the bootchart collector. But in your dmesg I can see this

[ 2.832955] Out of memory: kill process 110 (collector) score 51 or a child
[ 2.832963] Killed process 110 (collector) vsz:3268kB, anon-rss:512kB, file-rss:404kB

which looks a lot to me like OOM is killing your bootchart collector.

Later in the dmesg plymouthd and ureadahead is also OOM killed. I wonder why?

[Zachary Scott (zzak-deactivatedaccount)]

@Anders

Unfortunately neither am I and have no clue why I'm getting OOM errors with
4gigs of RAM, plus 1.7GB swap on my SSD..

I'm going to remove bootchart and see if that fixes the OOM errors
