That file could only be stuck if somehow the notifyqueue_running lock is stale or not being released. Maybe something in your notification settings is broken and it can't get messages out.

I'd make sure your ESX or VMWare install is completely current first, and upgrade the VM hardware compatibility as far as possible. Also make sure the selected OS version matches what you have installed. The exact text will vary depending on your ESX/VMware version but it should be set to FreeBSD 11.x 64-bit.

It might be an edge case we can't really detect well since it may be valid in some other way, even if it isn't an IP address (e.g. a hostname, other alias name, etc)

Soon.
