I am having the same problems for quite a while with an NFS mounted
/usr/port tree on my FreeBSD SMP machine (dated 09. Feb 97). Everytime
I try to compile things off /usr/ports that require some work to be
done, the NFS client side hangs. When this has happened, commands like
'df' etc also lock up completely so that they cannot be terminated.
Only solution is rebooting the client machine completely. The same
thing also happened quite some times while trying to mv files from
a local disk to an NFS mounted volume. The NFS server machine (FreeBSD
of same date as above SMP system but UP machine) does not seem to suffer
from that hangs in any way.
Regards, Mickey
