IDE Stability Fix

매 한 줄

"매 IDE crash / freeze / OOM 의 root cause 는 대부분 extension memory leak, large file indexing, TS server overload". 매 2026 의 Electron-based IDE (VSCode, Cursor, Windsurf) — 매 동일 패턴. 매 systematic disable + heap profiling 으로 해결.

매 핵심

매 흔한 원인

  • Extension memory leak: 매 disposable 미해제, listener 누적.
  • TS Server OOM: 매 large monorepo (>500k LOC), --max-old-space-size 부족.
  • File watcher exhaust: 매 node_modules watch → fs.inotify limit.
  • Renderer process freeze: 매 large file (>10MB) 또는 minified bundle 열기.
  • GPU process crash: 매 macOS Metal driver 충돌.

매 진단 도구

  • Developer: Open Process Explorer (VSCode)
  • --inspect-extensions=9229 + Chrome DevTools
  • code --status — running extensions + memory.
  • macOS Activity Monitor — Code Helper (Renderer) 의 RAM 추적.

매 응용

  1. Monorepo 의 TS server tuning.
  2. AI extension (Copilot, Cursor) leak 진단.
  3. WSL2 / Remote SSH 환경 stability.

💻 패턴

TS Server memory raise

// .vscode/settings.json
{
  "typescript.tsserver.maxTsServerMemory": 8192,
  "typescript.tsserver.experimental.enableProjectDiagnostics": false,
  "typescript.disableAutomaticTypeAcquisition": true
}

File watcher exclude

{
  "files.watcherExclude": {
    "**/node_modules/**": true,
    "**/.git/objects/**": true,
    "**/dist/**": true,
    "**/.next/**": true,
    "**/target/**": true
  },
  "search.exclude": {
    "**/node_modules": true,
    "**/dist": true
  }
}

Bisect extensions

# 매 extension 중 어떤 것이 crash 원인인지 binary search
code --disable-extensions  # 매 모두 disable → 재현 X = extension 문제
# Help → Start Extension Bisect 로 자동 binary search

Heap snapshot 분석

# 매 extension host heap snapshot
# Cmd+Shift+P → "Developer: Take Process Heap Snapshot"
# Chrome DevTools 에서 .heapsnapshot 열어 분석

Linux file watcher limit

# inotify limit raise (default 8192 매 부족)
echo fs.inotify.max_user_watches=524288 | \
  sudo tee -a /etc/sysctl.conf
sudo sysctl -p

Disable GPU acceleration (macOS crash)

# 매 Metal driver issue → software rendering
code --disable-gpu
# 또는 settings.json
"window.experimental.useSandbox": false

Cursor / AI extension throttle

{
  "cursor.cpp.disabledLanguages": ["plaintext", "markdown"],
  "github.copilot.editor.enableAutoCompletions": true,
  "github.copilot.advanced": { "length": 500 }
}

매 결정 기준

증상 첫 시도
TS Server OOM maxTsServerMemory 8GB
전체 freeze --disable-extensions bisect
GPU artifact --disable-gpu
File watch exhaust watcherExclude + inotify limit
Indexing 끝없음 search.exclude + remove large dirs

기본값: settings.json 의 watcherExclude + maxTsServerMemory 부터 시작.

🔗 Graph

🤖 LLM 활용

언제: IDE crash log 분석, settings.json tuning, extension 충돌 진단. 언제 X: 매 일반 app crash — 매 Electron-specific 패턴 만.

안티패턴

  • 무작정 reinstall: 매 cause 찾지 않음 — 매 재발.
  • Disable all extensions 영구: 매 productivity 손실 — 매 bisect 후 specific 만 disable.
  • Ignore log: 매 ~/Library/Logs/Cursor/ 또는 code --status 가 직접적 단서.

🧪 검증 / 중복

  • Verified (VSCode docs, Cursor support forum, GitHub issue tracker patterns).
  • 신뢰도 A.
