FreeBSD 3.0-Current as of 5/20/97
nfs-mounting one filesystem from a sun running SunOS 4.1.3_U1
 across an ethernet.

>Description:

	
When the sun's filesystem is mounted and the sun is down,
"df" hangs uninterruptably.

# df
^C^Z^\

% ps axl | grep df
    0 26409 10351   0  -1  0   208   76 nfsrcv D+    p0    0:00.00 df -k
 5275  4316  2590   0  -1  0   208    8 nfsrcv D+    p4    0:00.00 df -k
% mount | grep nectar
nectar:/nectar on /nectar/nectar

>How-To-Repeat:

	
Mount a remote filesystem from a sun running SunOS 4.1.3, then
halt the fileserver and run "df" (or "cd" or...) on the remotely
mounted filesystem.

>Fix:
	
	
unknown.
