chromium leaving zombies

I'm running an up to date arch system Linux bunyip 3.7.10-1-ARCH #1 SMP PREEMPT Thu Feb 28 09:50:17 CET 2013 x86_64 GNU/Linux

Chromium Version 25.0.1364.152 (185281) is leaving behind zombies. I googled some mentions of this, but there was no mention of a fix. Is this a known problem?

Re: chromium leaving zombies

You could try aliasing the launch command to something like "chromium && pkill chromium".


I laugh, yet the joke is on me

Re: chromium leaving zombies

The same is happening with Google Chrome Dev on AUR so it's probably not a package problem, i always need to kill the "chrome" process and also "Chrome_ProcessL", it's getting annoying.

Re: chromium leaving zombies

I find that trying killall chromium doesn't actually work to remove all the processes. I usually need to follow the chain of process ids to kill them all. In advanced settings I noticed a tick box marked [bold]Background Processes[/bold] Continue running background apps when Chromium is closed. I have unchecked that as presumably it might contribute. With all the checking of settings etc etc I noticed another 'feature'. If my usb dvb is running when I open up the settings page then vlc stops running (reselecting the channel starts it up again); weird. I guess chromium is probing something fairly hard which interferes with the pctv 290e.

Re: chromium leaving zombies

Not only a lot of zombies but also a big slowdown of all kde apps (dolphin, ecc). The only way is to kill not only chromium but all chromium related apps in Ksysguard.

Re: chromium leaving zombies

I run openbox so don't know about kde etc. I have noticed occasional problems opening up new browser tabs. Unfortunately, my unchecking the 'Continue running background apps' setting doesn't seem to have improved the situation. I still get zombies which need manual destruction.

i don't have browsed so much but seems that kde slow down problem is solved by disabling "GPU compositing on all pages" (sorry but is brutally translated from my locale) under about:flags

zombies always there

This happens and is VERY annoying. Hope chrome/chromium get patched soon...

Re: chromium leaving zombies

I have this problem too. I reverted to Chromium 25.0.1364.97-1, that one doesn't leave zombies.

Re: chromium leaving zombies

Do any of you use the extension Adblock?

I also have zombies and a few times upon startup my browser would hang with the message "waiting for adblock" - so I removed adblock and switched over to adblock plus and as of yet I've had no zombies...

May just be a coincidence, please report any success of this is indeed a cause of the zombies.

EDIT/ Oops don't forget to restart chromium after swapping extensions and kill any of the remaining zombies left over before performing tests.
EDIT2/ Nope they are back! Sorry for the noise!

Re: chromium leaving zombies

After the latest version 25.0.1364.172 (187217), the problem persists.

I think this dev thread

https://groups.google.com/a/chromium.or … Lf5l669dCk

is addressing the probable cause. Seems google started using their own malloc and that interacts badly with some things that nvidia is doing.

No issue here with nouveau driver, had the same issue with nvidia on another machine.

Re: chromium leaving zombies

This is pretty annoying, had to downgrade chromium as karabaja4 has done, hope they fix it soon

Re: chromium leaving zombies

I was able to fix this by switching to the  nvidia-304xx package (with lib32-nvidia-304xx). Nouveau also fixed it, but I need the nvidia driver for opencl in darktable. Hopefully the 313 package will be fixed soon.

Re: chromium leaving zombies

Both downgrading Chromium to 25.0.1364.97-1 or installing nvidia-304xx didn't help. You might think some of that helped because most of the times Chromium exits normally, until one time it leaves a bunch of processes running.

I wrote a small script to clean up Chromium processes after exit, use it to start Chromium. It requires wmctrl package.

#!/bin/bash

chromium

if [[ -z $(wmctrl -l | grep Chromium) ]]; then
    echo -e "\e[1;31mCleaning up...\e[0m"
    pkill -f /usr/lib/chromium/
else
    echo -e "\e[1;32mThere are still Chromium windows open. Not cleaning up yet.\e[0m"
fi

If anyone has a "softer" method of cleaning up processes, please tell.

Re: chromium leaving zombies

Sometimes I find that pkill chromium doesn't clean up all the stay behinds. I need two rounds of pkill to get them all.

Re: chromium leaving zombies

From the link from replabrobin in post #17

-Dlinux_use_tcmalloc=0

I compiled from ABS adding this in PKGBUILD in the gyp defines.
Tested with 75 loaded tabs across 3 windows and when I closed the windows no zombies at all.
