Memory increases

[ask4kapil]

Hi I am using the angularjs app and I have questions regarding the memory management and routing.

I had tested this senario, one app with pure angular js and it has two routes, so when I nevigate between these two routes for 20 times then browser memory increased by 150 MB.

what is reson for this? Is there any setting though which I can controll this?

This sounds like a bug. Can you please provide a minimal example that we can run locally or in a plnkr that shows the problem? Also, what browsers are you using? Do you see the memory increase in the browser dev tools or in the task manager (equiv).
There are also these topics, which describes a similar problem, maybe this is the same: #8061 #3543

Seems to the Issue with jquery only... let you know once I will test with jquery 1.9 version

[Narretz]

For angular 1.2, only jquery < 2.x is supported. On master, starting with the next beta we will support only jquery >= 2.0.

Hi Narretz,

The app which I had created seems to be very big, so I can not have the plnkr example but sure I can give you the elements which I had used in this mostly.
Elements are

• Nested ng-repeat on views
• grids
• tabs

I am seeing the memory increase in the chrome task manager, and with jquery 1.9 its improved with 20 routing now memory increase from 37 mb to 100 mb.

We upgraded a largish AngularJS application (25k lines of Javascript not including libraries, 20k lines of templates) from 1.3.0-beta.6 to 1.3.0-beta.17 and saw a tremendous increase in memory, with memory apparently not being reclaimed properly (usage grew and grew). Of course, I haven't come close to developing an simple example demonstrating the issue; just wanted to say that there does seem to be something afoot.

Not sure if @kapilkumawatca is running 1.2 or the 1.3.0 beta though.

Hi, i've got the memory leak too. I'm using ui-router and after 20+ state changes, memory significantly increases.
We don't use jquery.

[IgorMinar]

it would be good to get more info about this. none of our current memory leak detection tests fail, so it's not clear to me what the problem could be.

[IgorMinar]

@tbosch we should investigate this

[tbosch]

@alexandr2110pro @zachsnow @kapilkumawatca We really need a live example that reproduces the problem, including exact browser version. Could you try to create one that shows the problem? Could also be a live site, ...

Moving this to purgatory until we have better reproduction.

[IgorMinar]

we should at least verify that a common scenario (router with a repeater)
doesn't leak before moving this to purgatory

I'll make a plunker and take a look

[jeffbcross]

I created a plnkr with two views that contain nested repeaters with 1000 rows and 20 columns, as well as one mostly empty view. I recorded the timeline (attached) and clicked through all three views about 20 times (see orange marks at top of timeline created via console.timeStamp()). We could not reproduce the problem so far. If anyone wants to fork this plnkr and make it reproduce the error, that would help us identify any issues.

Per some discussion with @tbosch we decided to move this to purgatory until more concrete information is provided.

[IgorMinar]

I'm closing this as a dupe of #9095 which seems similar to the original report and is a confirmed leak.
