Debugging : V8 error: Allocation failed - process out of memory (Chrome 46)

[Mark Boas]

Hi - (Hope this is the correct forum for issues such as these) we're experiencing an intermittent tab crash on Chrome 46.

In order to try and debug I'm running Chrome from the command line:

$ /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --enable-logging --v=1

2015-11-16 14:02:15.343 Google Chrome[3537:1157640] NSWindow warning: adding an unknown subview: <FullSizeContentView: 0x7ff46171cca0>. Break on NSLog to debug.

Hi,

I think, problem is w.r.t some javascript function used by the URL. The problem looks continuous allocation of memory being made, after sometime, V8 returns allocation failed error. V8 returning error looks proper. We can try using V8 javascript profiler and try to see the JS function which is taking more CPU (which could be the place of more memory allocations too). With this, we can detect the JS function and the JS object which is allocated much memory. Thanks.

Regards,

Madan
