2 weeks ago It's looks like loop, tsserver takes 100% of one CPU core, and overall ts typehints became unresponsive. I assumed it was just indexing the project, but as it turns out, even if you leave it for an hour, nothing changes!
Then I open just small project with 100 lines - and it hungs as well after go to referece that leads to something external.
So I enable logging for tsserver to see where it create loop
The logs quickly went over 500 megabytes, and at first glance it doesn't look like it's a cycle
It requesting different lines and positions
