Description Robert Bost 2018-04-12 18:27:57 UTC
Description of problem:

Customer is having an outage due to their router pods being unresponsive. Removing health checks allows pods to start up but performing health checks manually (curl http://localhost:1936/healthz) still fail after a long pause with Connection Timeout.

Unfortunately, no events or logging output from haproxy.

Version-Release number of selected component (if applicable): atomic-openshift-

How reproducible: Happening constantly for customer.

Actual results: Unable to utilize pod routes.

Comment 3 Ben Bennett 2018-04-12 18:58:09 UTC
I think the iptables errors are a red herring since the router runs with host networking and a service is not being used to access it.

What's the cpu utilization of haproxy?  Is it under high load?
