Cluster members crash simultaneously when running kernel debug of Delta Sync and IPv6 traffic is passing through the cluster
Symptoms
  • Cluster members crash simultaneously when running kernel debug of Delta Sync ('fw ctl debug -m fw + sync') and IPv6 traffic is passing through the cluster, which is inspected by IPS (PSL).

  • The following stack appears on the console during the crash:
