Hybrid gateway crashes after load #1967

Closed ilijabojanovic closed 5 years ago

ilijabojanovic commented 6 years ago

Do you want to request a feature or report a bug? BUG What is the current behavior? When we send bigger traffic to salved gateway, gateway crashes after traffic What is the expected behavior? Gateway should not crash If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

  1. Start one or two slaved gateways
  2. Send traffic to those gateways

Gateway configuration:
