Apex extension has issue with cpu & memory consumption

[gbockus-sf]

This discussion is meant to track the ongoing issue of resource usage by the apex extension.

Root of the problem

The Language server used by the Apex extension is utilizing a package provided by the Apex team written in java that has the following resource usage on my MacOS laptop:
Memory : 530 MB

This is problematic on systems that are memory constrained and result in the APEX extension failing to load.

I'm starting this discussion to track the number of issues we have reported around this issue and to track potential solutions.

Troubleshooting

If you are receiving an "unresponsive" error, run the following commands in your project. The first will check to see if you have a stale Apex Language Server. Grab the process ID, and run it in the second command to reset it.

Mac

ps -eo pid,args | grep "[A]pexLanguageServerLauncher"
kill <process_number>

Windows

tasklist -> find something like [A]pexLanguageServerLauncher
taskkill /PID PID /F
