+# Bug Fix: EMFILE Error on Projects with node_modules
+
+## Issue
+OpenCode server would crash with "Too many open files" (EMFILE) error when 
+scanning projects containing `node_modules` directories. This happened because
+the file scanning logic attempted to index thousands of files in node_modules,
+exceeding OS file descriptor limits.
+
+## Root Cause
+In `packages/opencode/src/file/ripgrep.ts`, the `Ripgrep.files()` function
+only excluded `.git/*` by default. When scanning projects with node_modules
+(which can contain 10,000+ files), the combination of:
+1. fast-glob opening many files in parallel
+2. Additional direct filesystem checks
+
+Would exceed the file descriptor limit.
+
+## Fix
+Added default glob exclusion patterns for common dependency and build directories:
+- node_modules
+- bower_components  
+- vendor
+- dist
+- build
+- target
+- And 20+ other common directories
+
+These are now automatically excluded in both `Ripgrep.files()` and `Ripgrep.search()`.
+
+## Testing
+This directory serves as a minimal reproduction case. Run:
+```bash
+cd packages/opencode
+bun test test/file/ripgrep.test.ts
+```
+
+The fix has been verified to:
+1. Exclude node_modules from file scanning (4 files scanned vs 10,000+)
+2. Pass all existing tests
+3. Handle projects with large node_modules directories without EMFILE errors
