Memory leak?

[jrasanen]

Running npm-check reserved all the available RAM + ~15 GB of swap. Running this freezes my computer within seconds.

[lijunle]

Hmmm, this may relates to depcheck.

[dylang]

@jrasanen does it still happen if you use --skip-unused or -u?

[jrasanen]

Works much better with that flag, it only froze for couple of minutes. After consuming ram it takes swap around 15-25 GB. (Without this flag the swap file just kept growing until system freeze)

This is while system was unresponsive (with --skip-unused)

After waiting 2~3 minutes (with --skip-unused)

I've added a concurrency check so that it only checks the registry once per cpu. Can you try with --skip-unused again and let us know if he helps?

[kidwm]

@dylang npm-check -u -s use close to 8 GB memory in my case.

+1: Uses 16GB almost immediately for my package.json of about 60 libs.
