WAIT_TIMEOUT
The wait interval expired
WAIT_TIMEOUT is the normal timeout result from many Windows wait APIs. It does not by itself identify a failure in the waited object; it states only that the object was not signaled within the requested interval.
What to check
- Record the timeout and the object or condition being awaited.
- Distinguish polling timeouts from overall operation deadlines.
- Check whether the producer is blocked, slow, or no longer running.
- Avoid logging expected short polling timeouts as high-severity errors.
How to handle it
Continue, retry, cancel, or fail according to the caller's deadline policy. Always re-check the protected condition after a wait because notifications and state changes may race.
