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. -greg Machine: ======= FreeBSD server.example.com 7.3-STABLE FreeBSD 7.3-STABLE #36: Wed Aug 25 11:01:07 CEST 2010 root@server.example.com:/usr/obj/usr/src/sys/KERNEL amd64 Kernel was csup'd earlier in the day on 25 August, immediately prior to the build.
