I've begun seeing problems on a machine running FreeBSD-7.3-STABLE, 64-bit,
with two igb nics in use. Previously the machine was fine, running earlier
versions of 7-STABLE, although the load on the network has increased due
to additional machines being added to the network (the machine functions
as a fileserver, serving files to compute machines via NFS(v3)).
Any advice is much appreciated. System info is below.
