Something tells me (gut feeling) the virtualisation part is probably somehow responsible for the problem, quote: > I'm mounting the FreeBSD-server from a couple of vmware esxi 4.1 > servers using nfs, but when there is alot of i/o the server becomes > unresponsive, easily triggered by installing ie. ms-sql.

Can you remove ESXi from the picture and see if the problem continues? If it does, we should probably pull Jack Vogel into the discussion, as Supermicro predominantly uses Intel-based NICs. He'll need output from "pciconf -lvcb" and "dmesg" to assist. But before pulling him in, please see if you can remove ESXi from the picture. -- | Jeremy Chadwick [email protected] | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
