Diskless SLC error

[Lap Yun Yau]

We've setup our SLCs with external hard disks and they work fine, however,
when we put the SLCs as diskless clients of a Sun 4/490, the following
message appears on the SLC:

	NFS write error 13 on host sunkiss fh 1607 1 a0000 e8a2 3cb0ccd5 
					a0000 2 446047ba

This message will later repeat one more time and then lock up the console
screen (or console window if running sunview).

Anybody experienced similar problems?  I used standard setup as described
in the booklet "installing a Diskless SPARCstation Client" except the swap
is on partition other than /export/swap.  We are using SunOS 4.0.3.
