The issue has been reproduced under 3.1.4r57640 and 3.1.6r59338 using any virtual Intel NIC and Bridge/Host-Only networking. It does not occur using the PCnet/virtio adapters or NAT networking. Reproduction simply involves starting a VM configured for network boot, letting it connect, and performing a reset on the VM. It does not always occur, but frequently. Attempting to pause/close the VM results in an error such as: `Callee RC:` `Unknown Status 0x800706BE (0x800706BE)` VBox logs ending with a hang are attached.
