BD restarts and produces a core file
Traffic gets dropped while the ASM gets restarted.
A configuration change which involves headers configuration or a policy re-configuration and at the same time, while this update is taking place the ASM policy is removed from the virtual. This is more likely to happen in scripted tests than in the field.
Don't change ASM configuration at the same time as changing the virtual server configuration.
System will still restart but will not produce a core file when this happens.
