Getting GC, process out of memory error while bundling via webpack

Question

Getting following error when bundling my project with webpack. When I have only a few chunk (split) points (require.ensure ones) then it runs okay, but when I increase the split points following error comes.

Answer 1

This works when I'm increasing size of node, by default it's around 1GB (not sure exact)

Running node by increasing it's memory via --max_old_space_size=4092, it works
