JavaScript API website and Chrome memory issue

TomSellsted — Thu, 13 Nov 2014 16:12:36 GMT

Anybody having issues with large amounts of memory being used when looking at the ArcGIS API for JavaScript website using a Chrome browser? If I camp on that website, Chrome starts just using up lots of my systems memory. It takes a while though. This morning when I came in, it had allocated 2.8Gb of memory. As soon as I dismiss the tab, the memory is reallocated. Very weird... The same happens on the ArcGIS API for Flex too.

Tom,

Is it unique to your web app that you developed? I sounds like you have some code that is continually creating a new object (like in a loop or timeout) and never destroying it or setting it to null.

Robert,

Thanks for the speedy response. This is not an app that I developed. It is just browsing to the ArcGIS API for JavaScript website. Other browsers don't gobble up memory, but Chrome does.

Just navigate to: ArcGIS API for JavaScript using Chrome and open up the Task Manager. It takes a couple of hours, but it will start building up a large use of memory.

I use the API reference page a lot so I generally just camp on this website all day.

Thanks!

Best Regards,

Tom

Tom,

OK. Firefox is my primary browser and the one I leave the resources pages open with for multiple days. I will test this with Chrome and see if I can duplicate your findings.

I have had a tab open to the JavaScript API web site most of the day and it has over a gigabyte of memory consumed.

Here is the task manager arriving at work today...

Here is the task manager after dismissing the JavaScript API website tab.

Tom,

Yes. I can have Chrome open to the JS API Resource page and just watch the memory climb in Task Manager every couple of seconds.

Thank you sir! I am not exactly sure who to report this problem to. I was hoping that someone from ESRI would see this post and investigate. I have inadvertently left my Chrome browser open to this page overnight and had my system run out of memory.

Regards,

Tom

Thanks for reporting the memory issue. This affects, some but not all of the pages on the developers site. We will look into it more.

Bjorn,

Thanks very much for checking into this problem. I can see an improvement already!

FYI - it seems like this might have gotten fixed by Google fixing memory issues in the Chrome browser. It seems to be fine with version 39.

Bjorn,

I have been using version 39 and there still was a problem. It does appear that some modification was made though as I don't show any memory issues when viewing developer site pages today.

Thanks again for getting back to me!

Regards,

Tom

Tom,

I can confirm the same (no longer having memory issues).
