I remember seeing this behavior years ago when I worked at an ISP. Our
conclusion was that the OS (whatever version of Solaris was common about
8 years ago) had separate queues for each virtual interface. The queue
for the IP used by most clients could fill up, but there would still be
plenty of room in the queue for other IPs.
