Gaia VRRP member freezes when deleting a VLAN interface
Symptoms

  • Gaia VRRP member freezes when deleting a VLAN interface previously associated with VRRP.

  • The following message appears repeatedly on the console, in dmesg and in /var/log/messages files:
    unregister_netdevice: waiting for <Name_of_Interface.VLAN> to become free. Usage count = <N>

Cause

When the VRRP module fails to add a PARP entry to the Passive ARP Table table (add_parp_tbl), the device reference count is not released. This will lead to "unregister_netdevice" errors.
