Microsoft Azure Container Service Engine - Kubernetes

Known Issues

Node "NotReady" due to lost TCP connection

Nodes might appear in the "NotReady" state for approx. 15 minutes if master stops receiving updates from agents. This is a known upstream kubernetes issue #41916. This fixing PR is currently under review.

ACS-Engine partially mitigates this issue on Linux by detecting dead TCP connections more quickly via net.ipv4.tcp_retries2=8.
