P.S. I strongly suspect (although it is basically only a hunch) that it is the ads on the page that cause the leak.

Unable to reproduce the issue on Win-10 using chrome reported version #58.0.3029.110 and latest canary #60.0.3103.0.

Attached a screen cast and screenshot for reference.

Following are the steps followed to reproduce the issue.
------------
1. Navigated to https://seekingalpha.com/article/4073026-weighing-week-ahead-investors-fear-another-watergate
2. Observe that memory usage in windows and Chrome Task Manager. In chrome task manager it remained at a reasonable level i.e it did not cross 150 MB and fluctuated between 100 and 150 MB.

ianfarbrother@ - Could you please check this issue on latest canary #60.0.3103.0 by creating a new profile without any apps and extensions and please let us know if the issue still persist or not.

Thanks...!!

Thanks for trying to reproduce this - however, the screencast only shows 48 seconds. If you look at the Capture Folder image that I uploaded to show the capture times in my initial post, you will notice that the capture times are around 10 mins or so, and the whole process of 'zooming up' took around 35 minutes.

So I think you need to wait that kind of time in order to tell whether it is reproducible or not.

Btw, today I noticed it on another of the weekly series I read, this one coming out on Saturdays: https://seekingalpha.com/article/4074958-s-and-p-500-weekly-update-new-high-s-and-p-media-circus-arrives-scene?v=1495302823&comments=show

It would be difficult for me to run a setup with Canary (I think). I only have one machine, which is my *production* machine, so I am very cautious about messing with it.

It did, however, occur to me that perhaps I'm not the only one having issues with some SA pages, so I am about to send an email to their tech support (tech-issues@seekingalpha.com) and/or whether it might be related to the specific ads I am getting. I am going to refer them to this thread and ask them to respond here if they can contribute anything to the discussion.

I also noticed (from the small left-corner pop-up that says things like 'Waiting for <page>') that they seem to have some kind of ad refresh loop that seems to trigger roughly every 10 seconds or so.

As far as apps and extensions are concerned, the only two I have loaded are Session Buddy (hard to see how that could affect anything), and Ad Block Plus (which is obviously relevant). However, Ad Block Plus is disabled for SA, so I doubt that it would cause this kind of problem.

Thank you for providing more feedback. Adding requester "krajshree@chromium.org" to the cc list and removing "Needs-Feedback" label.

Well, I did a lot more experimenting this afternoon, while reading the latest installment of Jeff Miller's 'Weighing The Week Ahead' series. The short answer is that this now appears to be a problem with a *specific* ad on Seeking Alpha, rather than a Chrome problem. I will send this comment on to the SA tech people once I've finished writing it.

What prompted me to start this was that yesterday evening I started wondering whether the problem could be something in SA's javascript failing to release objects after using them. So I decided to check out Microsoft Edge. I also decided to see if I could induce the problem more easily on Chrome for reproducibility.

First, I found that the problem became more easily reproducible on Chrome simply by scrolling down the page - especially to the Comments section (and I noticed later, when I tried Edge, that this only shows up if you are logged in).

When I tried Edge - which was kind of a pain, although that was probably at least due in part to unfamiliarity with its controls - it initially appeared that I couldn't reproduce the problem. So, since the memory problem was such a nuisance on Chrome, I decided to go ahead and read it using Edge. It turned out that on a couple of the linked articles, I started seeing the problem, but still not on the main article, which seemed especially odd.

To cut a long story short, I eventually noticed that in the main article I wasn't seeing a particularly annoying ad from SRAX that only appears somewhat down the page (which is why scrolling is necessary in order to reproduce it), but then annoyingly follows you down the page as you continue reading. It also happens to update itself frequently, which I suspect is somehow at the root of the issue.

So, my best guess at this point is that there is no need for you to do any further work on this - at least until we get some kind of feedback from SA.

Thanks for your initial attempt to reproduce this ... Ian

Got a response from Seeking Alpha midweek to say that they have terminated the relationship with SRAX (yay!). Anyway, I've been monitoring things carefully since then, and have seen no sign of the problem recurring.

So you can go ahead and close this.

Thanks ... Ian

As per comment #7 , closing the issue . Please feel free to raise a new issue if you face any issues in latest chrome channels.

Thanks!
