FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Desired functionality.

I would like to be able the app using AOT.

Mention any other details that might be useful.

I have tried changing ng.cmd to this:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=8192 "%~dp0\..\@angular\cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=8192 "%~dp0\..\@angular\cli\bin\ng" %*
)

and ngc.cmd to:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=8192 "%~dp0\..\@angular\compiler-cli\src\main.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=8192 "%~dp0\..\@angular\compiler-cli\src\main.js" %*
)

I have 8GB swap file. The build fails after 20-25 minutes standing on 92% progress.

This is similar to #1652, but seems localized to AOT compilations. There might be improvements we can do to help.

I got the same issue too.

So, I tried to build the same project (@angular 4.0.0) using ng-cli 1.0.0-rc.4 and it works fine.
ng build --prod --aot

@angular/cli: 1.0.0-rc.4
node: 6.9.5
os: win32 x64
@angular/common: 4.0.0
@angular/compiler: 4.0.0
@angular/core: 4.0.0
@angular/forms: 4.0.0
@angular/http: 4.0.0
@angular/platform-browser: 4.0.0
@angular/platform-browser-dynamic: 4.0.0
@angular/router: 4.0.0
@angular/cli: 1.0.0-rc.4
@angular/compiler-cli: 4.0.0

I also want to add that even though I try to increase max_old_space_size by editing ng.cmd and ngc.cmd, it seems like the node.js process never uses more than 1600 MB of RAM according to the process monitor on my system, which is well within the limit i setup of 8192 MB and it still says "out of memory".

I have the same issue. my project works on cli rc.4. it fails when ng build --prod after update to 1.0.0.

[aminebizid]

I'm so afraid there will be no solution for this issue.
I reverted to rc.2 because of this :(

[efstathiosntonas]

In my case, I installed typescript@2.1.6 instead of @~2.2.0 and the memory issue went away. Give it a try.

There is an issue in ~2.2.0 and @angular/language-service 4.0.0 (in my case i use it)

[AngelVlc]

I've changed max_old_space_size in %AppData%\npm (Windows) and it works for me when launching ng serve with 1.0.0.

[aminebizid]

@efstahiosntonas are you using ng4?

[efstathiosntonas]

@Zigzag95 yes, ng4

[elvisbegovic]

same problem here

Thanks @AngelVlc !

Changing limit in ng.cmd under %appdata% did the trick! Now node.js uses around 4GB of RAM and the build is completed.

[chrisnicola]

I'm getting OOM errors with @ngtools/webpack 1.3.0 and @angular 4.0.0. This is on OSX and not Windows as well.
