5254	Host-only networking stops working	henrik242		"I use two network interfaces: one NAT and one Host-only adapter. The NAT interface works great all the time. The host-only interface, however, usually works as it should for a while after boot, then it becomes extremely slow and/or unresponsive.  All adapters (Intel and PCnet) are affected.

A VM reboot might help, but sometimes it must be shut down completely. 

This is a Mac OSX 10.6 host with a Debian testing guest (kernel 2.6.30-1).

A similar problem is [http://forum.virtualbox.org/viewtopic.phpf=6&t=19457&start=30&sid=d2fa7b3d50bc97a49f596a0df94743ce discussed in the VirtualBox forum], and  tickets #1256 and #4870 might be related.
