Extension host terminated unexpectedly.

Issue Type: Bug

It seems to be something memory related, but I’ve about 3Gb of free RAM according to HTOP.

Started: This issue started yesterday (10/12/2019)

Tried: 1 - Reinstalling Extension 2 - Clean VSCode install (removed caches and all folders from system).

To Reproduce There’s no step to reproduce it. Extension host crashes after 1 ~ 5m. If I disable the extension, the crash stops.
