I am using Astronvim community tailwind package with default config https://github.com/AstroNvim/astrocommunity/blob/4d8d63458cea63e704e0f08eeaf4d4c3330e19d4/lua/astrocommunity/pack/tailwindcss/init.lua

Regular (every day at least, usually often) tailwind language server is down because of memory:

Interesting. I don't see this… ever. Any chance you could provide some more details about the kind of project(s) you use it on?

This is one of monorepo (turborepo) project. Next.js

[thecrypticace]

• How large is the project? (number of files, number of packages, etc)
• Do you have multiple installations of Tailwind CSS in that project or one shared installation?
• How many tailwind configs do you have in your project?
• Any chance you could provide LSP logs up to the point where the crash happens?
