IntelliJIdea2017.2 fails to index project

Try starting with default settings: (rename/remove IDE settings and caches folders).

If issue remains describe exactly what happens (how it crashes). Are there java crash logs (files with names like `java_error_in_idea_*.log` in your user home directory)?

The last few times that it has been happening, it got to <PROJECT>/buck-out/gen/lib/scala-compiler-m...

I have buck-out marked as excluded.. I thought that would prevent indexing.

cpu goes up to ~800 (all my cores), and I have to kill the process before it crashes my machine with the beach ball of death.

no error logs in the home directory

There are a lot of these in the threadDump-<date>.txt:

I tried renaming the cache and settings folders

I

I just moved the plugins directory as well, and that seems to have resolved it... no idea which plugin was causing me issues though... I might get back on to you if it happens again :) Thanks

Try also updating to the latest IDE version from https://www.jetbrains.com/idea/download.
