JavaScript heap out of memory and Helix says language server has exited #1342
Description
Code editor
Helix
Platform
Linux, Debian 13
Version
5.4.3
What steps will reproduce the bug?
Sometimes the server crashes and Helix warns the language server has exited, I can't reliably reproduce, but here is the log and below the script that was being edited in the most recent occurrence:
