…loses openclaw#104) Playwright's connectOverCDP() attaches to ALL open pages during initialization. If any page's renderer is stuck (e.g. TradingView with heavy JS), the entire connection hangs indefinitely. Add a pre-connection health check that probes each page via raw CDP Runtime.evaluate("1") and closes unresponsive pages before connectOverCDP() runs.

After a gateway restart, Chrome's SingletonLock/SingletonSocket/SingletonCookie files persist on the Docker volume while their /tmp targets are gone. This causes Chrome to hang or timeout on subsequent launches. Remove these files in launchOpenClawChrome() before spawning, which is safe because ensurePortAvailable() already confirmed no Chrome is running on that port. Closes openclaw#55 Co-authored-by: Claude Opus 4.5 <[email protected]>

Summary
Runtime.evaluate("1")and closes pages whose renderer doesn't respond within 3sconnectOverCDP()from hanging indefinitely when a tab with heavy JS (e.g. TradingView charting) is open.catch(() => {}), falls back to existing retry logic if eviction failsCloses Milofax/marakanda-infrastructure#104
Root cause
Playwright's
connectOverCDP()attaches to ALL open pages during initialization. If any page's renderer is stuck, the entire connection hangs. Confirmed by closing the stuck tab via raw CDP — Playwright then connected in 63ms.Test plan
