Desired functionality.

After updating a project to CLI v1.5.0 builds with aot and build-optimizer should be successful

Mention any other details that might be useful.

I'm working with an existing medium to larger sized app and can build with AOT using cli v1.4.9. Using --build-optimizer failed with the same result as above so I tried updating my CLI to 1.5 to see if there were any improvements and can no longer build with AOT. The build will process for 15-20 minutes then crashes with the output above. At first I thought it could be related to devkit #240, but after running the build again with --build-optimizer=false the out of memory crash reoccurred. I am only able to successfully build by disabling aot and build-optimizer.

I'm having the same issue since 1.5

I'm having the same issue in 1.4.2
But i try to increase node max_old_space_size when build
node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build --prod
It work for me.

[williangd]

Same problema since 1.3 :(

Using node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build --prod too.

@williangd
I try to increase --max_old_space_size=4096 to --max_old_space_size=5120 It work.

[bniedermeyer]

I agree that manually increasing the node memory allocation during a build will help it to succeed - but isn't this more of a red flag that something wrong is causing the cli to use a large amount of memory? Suddenly having to increase memory after a minor version bump is a bit concerning to me.

If this is to be the accepted norm I would be happy to put together a PR to document it so others don't think something is wrong, but would like confirmation from someone like @filipesilva first.

This solution does not work for containers like travis..

[PillowPillow]

Working on a large application i simply can't build anymore with AOT even increasing the memory to 5g..

[rbluethl]

I really appreciate your great work on Angular so far, but I have to say that it worries me that every minor update lately basically causes another error that crashes our production build and thus throttles our entire development process. Having said that, we're still dealing with the described problem as well...

I have the same issue when using --stats. Note: I have to use Typescript 2.6.1 because despite the warnings, Angular and Rx do not build with anything less than 2.5.0 (there are other open issues).

[ellesse]

Same issue with a medium-large application when trying to upgrade to angular cli 1.5.0 and angular 5.0.0.

[damiandennis]

Also having same issue since upgrading to angular cli 1.5.0 and angular 5.0.0.
