bug: macOS sleep/resume can trigger EMFILE and spam long plenary Job stack traces (copilot token refresh) #2815
Description
Describe the bug
Repeated/large error output like: ...plenary/job.lua:406: Failed to spawn process: { ... pid = "EMFILE: too many open files", ... } (full stack trace repeated many times), makes Neovim usable.

To reproduce
- Neovim running with avante.nvim + copilot provider enabled on macOS.
- Put macOS to sleep (close lid / sleep) for a long time(one day maybe), then wake the machine again.
- After wake, avante.nvim triggers copilot token refreshes and plenary Job spawn fails with "EMFILE: too many open files", spamming the Neovim message area with full plenary stack traces.
Expected behavior
Handle spawn errors more gracefully like #2356 or Exafunction/windsurf.nvim#297
Installation method
Use lazy.nvim:
-- "yetone/avante.nvim",
-- if you want to build from source then do `make BUILD_FROM_SOURCE=true`
-- ⚠️ must add this setting! ! !
build = function()
-- conditionally use the correct build system for the current OS
if vim.fn.has("win32") == 1 then
return "powershell -ExecutionPolicy Bypass -File Build.ps1 -BuildFromSource false"
else
return "make BUILD_FROM_SOURCE=true"
end
