That's nothing in fact..., if i may say so:)! Lol?

CheeRS Mi aka the penguin....<("),
who is supposed to work some:(!

(The 'boss' is just in front of me, in some calculations.., as i'm 'documenting' in the meanwhile, many others topics:)!

'top' command gives U main process 'running'.. i say 'naturaly' on the L.T. working as 'server'.. whom 12.9% of CPU only is/was in use 4 many 'services' running at the same time...Smile!

Note : We have left M$ systems.. to work 'seriously'... as/in some technical calculations... among others activities:)! I garanties i'm on everyday little... 'improvements', well when i can indeed and computers works everyday:)!

(Just to say.., hundreds of services in run... but a very few, in charge... numerous pages and duties on, and all that took only 12% of CPU.. at the top of use... Smile!

We call that 'system' and in fact, i'm introducing U to some 'hacking'.. that's mean in realyty... i brought U to study some point a system in a technical point of view:)!

Okay, we goes back on GDB backtrace generating.. and as i need the identity of the process :

mezig@mezig-desktop:~$ pidof chromium-browser
19264 19262 19260

(That's a 'bug' i search... first in Chromium-browser, i use some now and who is just out of Beta version....Sad! That's mean, some issues maybee:)?

Note all that i do, is following the documentation ther is there :

http://dev.chromium.org/for-testers/bug-reporting-guidelines/reporting-crash-bug

and there, as the computer is always running... it's little personal 'server' version/application.. usualy with a very long uptime.. thus new kernel's update under Ubuntu, needs to restart the computer in fact:(!

4 me it's a shame.. as if it's goes on in that way... we 'll have soon an OS called Win-nux or Lin-dows...Smile?

Note and out of jokes a 'Bridge' already called Lindows already exist...! Supposeed to be a passerelle between the two OS.... sponsorized, by IBM and some M$ behind i think...Sad?

I'll do an article later on that, if i have time:)!

I'm also reading some of the page of :

https://wiki.ubuntu.com/Chromium/Debugging

as i have some freeze... in GDB... so i use the continue fonction :


(gdb) continue
Continuing.
waiting for new child: Aucun processus enfant.
(gdb)

Well in fact cause i need to pass on the next pid number:)!

Note.. apparently all is done already.. among all the pid i have..., and i'm obligent to do all that by hand.... or with my stiky fingers:), cause the Chromium issue report is searching his way since i try it...., and than the

'report state' included in /chromium/profile leads nowhere : i.e. there :

'In Chrome profile directory (~/.config/google-chrome) there is a file called Local State. Open this file in any text editor and search for 'client_id'. If you find this string in the file, please copy that line and paste in your bug description.'

Note than 'indeed'.. some bugs occured and Chromium after a new froze, crashed once again:(!

I report that time.. the bug circonstancies... for the first time in fact and sent them to that page 4 all the details i put on it... in the hope it may help some... and Buzz a little our page 2:)?

I'm gessing some troubles about Flashplayer.. who is so few 'free' than i'm sure ther si many stash in it, than we can't solve... as indeed owned source code is keept 'secret'Sad!

Then or before.. mind to read and see what's on or already solved among the Google wiki pages, at :

http://www.google.com/support/chrome/bin/request.py?confirm=google_feedback&ctx=go
