cache files are randomly corrupted

[jooddang]

Hi,
I'm using cache-loader v1.0.3, and I love it for it saves a lot of webpack build time. (~1min)
The problem is that coworkers randomly experience build error of Empty files. It happens from our build machines a lot randomly, so we stopped using it recently. Can you find the root cause of it? Stack trace is as below:

Empty files:

@jooddang can you create minimum reproducible test repo? Thanks!

[jooddang]

@evilebottnawi This is kinda bare minimum repo.
https://github.com/jooddang/cache-loader-test
The real repo is much more complex than this, but I guess this is what you would need for investigation.

Hi @evilebottnawi,
Can you take a look at this issue please?

[alexander-akait]

@jooddang can't reproduce, which OS and node you use? Also i recommend to upgrade webpack to 3 version

Thanks for the heads up. Yah, after upgrading to Webpack 3 that issue disappeared. I think it's good to close this ticket. :) Best, EunKwang

well, even after webpack is upgraded to v3, it sporadically happens, not reproducible on my machine tho (reported from co-workers).
Is there possibility that can make trouble when webpack.watch() runs concurrently with express server (for HMR)?
