HAPROXY routers are getting slow response and applications are getting 503 error
Issue
- Many applications are impacted as they are getting 503 error from haproxy routes. All those applications are up and running.
- tcpdrop and tcpretrans show dropped and re-transmitted packets that cannot be seen in a traffic capture on the outgoing interface, although strace shows them as written to the socket file descriptor.
Environment
- Red Hat Openshift Container Platform
- Twistlock 3rd party security application (or any other security application that uses nf_queues)
