How to tell Chromium-browser to run a url as single instance not multiple instances?

Question

I have a web application which crawls data and any browser download it first the second one will not get that crawl informations.

While using Chromium-browser in a PC i start as below:

$ chromium-browser -kiosk "http://pbx/adminkiosk/index?language=EN&username=2002&password=1234" &
sun@sun-Alienware-X51:~$ ps aux | grep "chromium-browser"
sun      31816  0.7  1.5 613092 61384 pts/4    Sl   15:44   0:03 /usr/lib/chromium-browser/chromium-browser -kiosk http://pbx/adminkiosk/index?language=EN&username=2002&password=1234

Now because 2 instance opening 2 url the data that gets crawled is delivered to other instance without balance. As a result my apps does not work with Chromium but works with Firefox/Opera.

How can i tell Chromium to stop this? And run the url only with one instance not twice??

EDIT:

I tried flags but no luck

--process-per-site  
--single-process

There are many explanations to why this may be happening.

I remembered Chromium is also auto-launching a GPU process (not on my laptop, though), and since you're using Alienware I suppose you have the GPU process "sleeping" with 0% use waiting for some graphics to display.

I suggest you try the following flags:

--disable-gpu-process-prelaunch --disable-software-rasterizer

to disable GPU (and extras)

or this flag:

--in-process-gpu

to run it as a thread

you can also try

process-per-tab

but it seems like you've tried something similar which wasn't of aid.

please report back with your findings :)
