Set it in > /boot/loader.conf. Indees it does. I raised it to 65536 and now I can copy large files =20 and do not see "NetGraph data items" failures in vmstat -z anymore. I wonder whether it could be a recommendation of the VirtualBox ports? =20 I am not the first one to be bitten by it so it would make sense to =20 send a warning. E.g. Marlon discarded the whole FreeBSD/VirtualBox setup and went =20 Citrix instead. It does not have to be like that;-) In one way it makes sense that the _start_ of the VirtualBox makes the =20 difference. It is a busy company mailserver with SMTP and HTTP access =20 and a lot of traffic going through - it all has to go through the =20 netgraph items. Of course, I have in my setup another way of working around the =20 problem: at the moment VirtualBox is using the same interface than the =20 host. I have a still unused interface I should use instead to separate =20 the traffic. Regards Peter
