3.36.10. UseStatusServerForFailureDetect Previous topic Parent topic Child topic Next topic

If this optional flag is enabled, use only Status-Server requests (if any) to determine that the target server is failed when there is no reply. If not enabled (the default) use no-reply to any type of request. Uses NoreplyTimeout, MaxFailedRequests and MaxFailedGraceTime during failure detection.
FailureBackoffTime has no effect when UseStatusServerForFailureDetect is enabled; once a Host has been marked as failed, it remains marked as failed until a reply is received from it (typically in response to a subsequent Status-Server request).
If you enable this, you should also ensure KeepaliveTimeout is set to a sensible interval to balance between detecting failures early and loading the target server.
