Describe your issue

When working in a project with Tailwind CSS, the Tailwind CSS IntelliSense extension spawns a large number of helper processes. In the system monitor they appear as multiple code processes, each consuming around ~19–20 MB of resident memory.

In total, these processes accumulate to approximately 3–4 GB of RAM usage.

From the process details, they appear to be related to the extension helper:

bradlc.vscode-tailwindcss/dist/oxide-helper.js

Example command line from the system monitor:

/snap/code/.../extensions/bradlc.vscode-tailwindcss-0.14.29/dist/oxide-helper.js

Observed behavior:

  • Opening a workspace with Tailwind enabled spawns dozens of helper processes
  • Each process uses ~20 MB of memory
  • Memory usage grows to several gigabytes
  • The processes remain running even when editing a single file

Environment details:

  • VS Code installed via Snap
  • GNOME System Monitor shows the processes under snap.code.code
  • Many processes are waiting on ep_poll

Expected behavior:

The extension should ideally use a small number of worker processes instead of spawning dozens of separate processes that collectively consume several gigabytes of RAM.
