      This is a clone of issue OCPBUGS-27959. The following is the description of the original issue:

      In a CI run of etcd-operator-e2e I've found the following panic in the operator logs:

      E0125 11:04:58.158222       1 health.go:135] health check for member (ip-10-0-85-12.us-west-2.compute.internal) failed: err(context deadline exceeded)
      panic: send on closed channel
      
      goroutine 15608 [running]:
      github.com/openshift/cluster-etcd-operator/pkg/etcdcli.getMemberHealth.func1()
      	github.com/openshift/cluster-etcd-operator/pkg/etcdcli/health.go:58 +0xd2
      created by github.com/openshift/cluster-etcd-operator/pkg/etcdcli.getMemberHealth
      	github.com/openshift/cluster-etcd-operator/pkg/etcdcli/health.go:54 +0x2a5
      
      

      which unfortunately is an incomplete log file. The operator recovered itself by restarting, we should fix the panic nonetheless.

      Job run for reference:
