# Worker Wedged Error • AI Agent SDK

> WorkerWedgedError: Raised when a session's turn worker is wedged / unresponsive.

# WorkerWedgedError

<Badge color="blue">AI Agent</Badge>

Raised when a session's turn worker is wedged / unresponsive.

Signals the gateway that the placement's worker can no longer make
progress (a wedged loop, an unresponsive subprocess/container, a lost
remote worker). The gateway responds by tearing down *only* that
placement (:meth:`TurnExecutorProtocol.teardown`) and re-placing the
session, rather than the process-wide `os._exit` that a single shared
loop forces today. Distinct from ordinary turn errors, which surface as
the turn's own exception and do not condemn the worker.
