Troubleshooting Tip: Cannot delete no-reference object
| Description | This article describes the behavior where it is impossible to delete the FortiGate object that has no references or its references were deleted. For example, the IPSec phase1-interface or SLA performance object, with the following error:
"...FW(health-check) # delete SLA_01
The only way to delete those objects is to reboot the Firewall, which is not always possible in the production environment. |
| Scope | FortiGate. |
| Solution | Check after connecting the console cable if the console keeps printing output like the one given below:
"...FW (health-check) # unregister_netdevice: waiting for .... to become free. Usage count = 105 ..."
Workaround: Disable the 'net-device' in the 'phase1-interface' settings of the IPsec Tunnel.
config vpn ipsec phase1-interface edit vpn1 set net-device disable end
This behavior is a known issue and can be tracked as per Bug ID: 1033154. As per the release notes 7.2.11 Release Notes |
