 I tried FTP (to have something completely different) and it fails as well:

I watched vmstat -z, and every time it fails, I have another failure
reported for "NetGraph data items".

Does raising the value of net.graph.maxdata help?  Set it in
/boot/loader.conf.

Indees it does. I raised it to 65536 and now I can copy large files and do not see "NetGraph data items" failures in vmstat -z anymore.

I wonder whether it could be a recommendation of the VirtualBox ports? I am not the first one to be bitten by it so it would make sense to send a warning.

E.g. Marlon discarded the whole FreeBSD/VirtualBox setup and went Citrix instead. It does not have to be like that;-)

In one way it makes sense that the _start_ of the VirtualBox makes the difference. It is a busy company mailserver with SMTP and HTTP access and a lot of traffic going through - it all has to go through the netgraph items.

Of course, I have in my setup another way of working around the problem: at the moment VirtualBox is using the same interface than the host. I have a still unused interface I should use instead to separate the traffic.

Peter
