I'm encountering this error whenever my SWF Worker application polls. If there's an entry in the SWF queue, it gets processed properly. But if it's empty, this timeout exception is returned.

What's causing this?
I'm using this setup:
@Workflow
@WorkflowRegistrationOptions(
defaultExecutionStartToCloseTimeoutSeconds = 259200, //3 days
defaultTaskStartToCloseTimeoutSeconds = 180
)
