x/tools/gopls: Out of control memory and CPU usage #44981
Description
ATTENTION: Please answer these questions BEFORE submitting your issue. Thanks!
What did you do?
Opened a brand new go file in neovim with the vim-go plugin.

Reasonable resource consumption
What did you see instead?
Multiple CPUs spinning constantly, while gopls continues to allocate massive amounts of RAM (8+ GB). Even after exiting neovim, gopls continues to allocate memory.
