Tern Content Assist Hangs and Out of Memory #424

This started happening just yesterday for no reason (nothing in Eclipse was changed).
Tern's Content Assist times out every time. It also has issues synchronizing script resources, it gets to around 93% and then just hangs there until it runs out of memory. After this started happening I checked for and updated Tern to the latest release, it's still having issues.

Here's the stack trace for when it runs out of memory.

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

It's little hard to help you with your info. Could you share your project please?

Whoops! Meant to reply to this way sooner, but got busy.

I can't share the project itself, but I can share the JavaScript resources and project config/settings
https://github.com/Knight-Yoshi/terntest

As I said I didn't change anything in Eclipse itself and it was working fine two days ago and the issues only started yesterday afternoon.

May be worth noting that yesterday morning my system did perform an update and other Eclipse plugins had a few problems, like EGit saying a perference node had been removed.

I replaced that installation of Eclipse with a new one and a fresh copy of Tern. Other plugin issues were resolved, but Tern still times out. Maybe it's an issue with Node then?

Try to exclude vendor folder by adding it with JavaScript/Include Path and add exclusion like **/vendor/*
