Yes, I think the timeout needs to be configurable. However, the only action that makes sense is stop. Everything else would be unsafe because the running request could still complete at a later point. Another question I have related to safety is whether (and how) you can migrate away from a host that has been stopped because of a timeout. I guess migration needs to be blocked then? Kevin
