node webpack hangs. How to debug?

I am trying to build ORO Platform js assets, using a non-docker environment, it works like a charm, but in Docker (either during Docker Build, or container execution) the building process stop and hangs with 100% CPU.

67% [0] building 1416/1470 modules 54 active ... ndles/orotask/sidebar_widgets/assigned_tasks/css/styles.scss

The building process does not necessarily hang on the exact same file. And also, the build seems to succeed on some occasion.

I've try to reduce to a minimum the process by removing Happy, tested with --max-old-space-size=4096, but no luck.

How would you recommend debugging this ?

Thanks

Solution

  • There is a known issue when a NodeJs process hangs while you run it from the root user. As I know, there is no workaround for now. Consider using another user to build the assets.

    If it's not the case, please review the Troubleshooting section in OroAssetBundle, that might help.
