The box is a diskless X workstation, which boots via pxe/tftp from another 5.2.1 FreeBSD System. The root filessystem is provided via nfs from that box, too. That makes it very inaccessible for now, since nfs hangs at every few chunks of file access. It worked fine with 5.2.1-RELEASE. Since the upgrade to 5.3-BETA6, i expierience NFS stalls. In 5.3-BETA6, i found the problem to be NFS errors (according to tcpdump) and TCP problems (impossible window sizes and error messages on the console regarding that). I tried to switch NFS mount options from -3 -T to plain v2/udp, but it didn't help much (although the box did run a few more minutes). Also the BETA7 upgrade did not fix the problem. Also interessting is, that netpipe benchmark seems to hang, too. In tcpdump it looks like the ACK's are not send in time (e.g. hang for a few seconds), but i am not sure at that. Another BETA7 box works just fine in that case, it has an INTEL 1000pro Desktop adapter. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
