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-3.3.1.17-1.git.0.b82e86c


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?
