try to modify the files and replace their contents with the following: (in the folder : node_modules\bin)

Modify ng.cmd:

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=5048 "%~dp0\..\angular-cli\bin\ng" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=5048 "%~dp0\..\angular-cli\bin\ng" %*
)

Modify ngc.cmd :

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe" --max_old_space_size=5048 "%~dp0\..\@angular\piler-cli\src\main.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node --max_old_space_size=5048 "%~dp0\..\@angular\piler-cli\src\main.js" %*
)

for angular 7, I increased the maximum memory allocated for budgets in angular.json file.

"budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "2mb",
                  "maximumError": "11mb"
                }
]

then ran the following mand: node --max_old_space_size=10500 'node_modules/@angular/cli/bin/ng' build --prod

in your case you should try to run this: node --max_old_space_size=10500 'node_modules/@angular/cli/bin/ng' serve --aot

This issue es if the angular app will bee bigger in size to pile. Please increase your node ram memory that will solve the issue. (Default node ram memory is 1600mb, increase it to around 3200)

I had the same issue In my tsconfig.json i had

"include": [ "**/*" ],

after removing this include, the ng build behave normal again
