Networking and Router Problems in Red Hat OpenShift Container Platform

Solution Verified - Updated -


  • Our ha-proxies have a pretty high restart count (> 300 in a few days). As they do not log much, I can just provide you those outputs. Any ideas how to debug this further? In the logs we see:
1201 08:42:28.395691  1 ratelimiter.go:50] error reloading router: wait: no child processes
  • Occasionally we report pods which are failing to connect or resolve a service name within the OpenShift cluster. After a few seconds it starts to work again and we have no idea where this is coming from.
  • I'm having weird networking problems in my OpenShift cluster and I see the following messages reported on my nodes
Dec 06 09:39:11 ose3-node1 kernel: net_ratelimit: 119 callbacks suppressed
Dec 06 09:39:17 ose3-node1 kernel: net_ratelimit: 154 callbacks suppressed
