Both machines have static ips.
Client has mounted this:

Client:~>mount
/dev/da0s1a on / (ufs, NFS exported, local)
devfs on /dev (devfs, local)
/dev/da0s1e on /tmp (ufs, NFS exported, local, soft-updates)
/dev/da0s1f on /usr (ufs, NFS exported, local, soft-updates)
/dev/da0s1d on /var (ufs, NFS exported, local, soft-updates)
procfs on /proc (procfs, local)
fdescfs on /dev/fd (fdescfs)
Server1:/sys0 on /nfs/serv0/sys0 (nfs)
Server0:/usr/ports on /nfs/serv4/usr/ports (nfs)
Client:~>

As stated before, it locks up on a portupgrade of p.e. imake, while
un-tar-ing the X sources, which come from Server1 (/usr/ports/distfiles
-> /sys0/distfiles) and get unpacked on Server0...

So reading from one NFS server, writing to another...
