Ticket #7404 (new defect)

|Host type:||Mac OS X|
I'm using virtualbox 3.2.8 on Mac OS Snow Leopard. I have 2 NetBSD virtual machines that have 3 network cards: 1) NAT 2) host only to do NFS to host 3) internal network to do network testing
When I leave the machines idle for some time, half hour to an hour, and then come back to them, the host only network dies. They can ping each other through the internal network and they can ping the outside world through the nat, however they are unable to ping the host through the host only and the host cannot ping the guests through the host only network. Watching tcpdump on the guests, I see traffic going out, but nothing coming in. If I keep a ping going continuously I find that I will get request timeouts for 50 or so messages and then they'll all come in at the same time.
Right now the workaround is to suspend the guest(s) and then start them again, then everything is fine.
