Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: If a pod using an egress IP tries to contact an external host that is not responding, the egress IP monitoring code may mistakenly interpret that as meaning that the node hosting the egress IP is not responding. Consequence: High-availability egress IPs might get switched from one node to another spuriously. Fix: The monitoring code now distinguishes the case of "egress node not responding" from "final destination not responding" Result: High-availability egress IPs will not be switched between nodes unnecessarily.
