verified in atomic-openshift-3.5.5.31-1.git.0.b6f55a2.el7.x86_64, no panic found in router logs by the script:

#!/bin/bash


function _simulate_eq_panic() {
    sleep 0.0$((RANDOM%3))
    echo "  - worker name: $1 ... "

    case "$((RANDOM%3))" in
      0)  oc create  -f "$2"  ;;
      1)  oc replace -f "$2"  ;;
      2)  oc delete  -f "$2"  ;;
      *)  oc replace -f "$2"  ;;
    esac

}  #  End of function  _simulate_eq_panic.


#
#  main():
#
routefile=${1:-"https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/unsecure/route_unsecure.json"}
ntimes=${2:-50}

for i in `seq ${ntimes}`; do
  _simulate_eq_panic "worker_${i}" "${routefile}" &
done
