#674: Any failed request should be enough to decide backend is sick
-------------------------+--------------------------------------------------
Reporter: istenrot | Owner: phk
Type: enhancement | Status: new
Priority: normal | Milestone:
Component: varnishd | Version: trunk
Severity: normal | Keywords: saintmode probe backend
-------------------------+--------------------------------------------------
As of Varnish 2.1.0 only failed probe requests can switch backend's status
from healthy to sick. Any failed normal request should be also a clear
signal to Varnish that a corresponding backend has gone sick.
The problem is that saintmode doesn't get activated until a probe request
has been made and decided as failed. That may result publishing 503 errors
for many seconds depending on probe request interval setting.
