>Environment:

	Client machine is a 3.0-current as of 03/16/97 with an NFS mounted
	/usr/ports filesystem which comes from a FreeBSD 3.0 machine which
        runs a -current that is 2-3 months older.

>Description:

	Doing a ''make clean'' in /usr/ports/x11/xview-config on the NFS
	client machine, after it has previously been extracted and built,
	causes the NFS client machine to crash without any trace. I suppose
	this happens due to heavy I/O especially when using this port, since
	the original archive is somewhat huge. Doing the ''make clean''
	on the NFS server machine did not show any unexpected behaviour.

>How-To-Repeat:

	Take an older 3.0-current equipped NFS server machine and mount
	/usr/ports from that server onto a fresh -current machine as a client.
	Then cd /usr/ports/x11/xview-config and try to ''make extract configure''
	and afterwards ''make clean''.

	This crashed both of my NFS client machines which both mount /usr/ports
	from a somewhat older 3.0-current NFS server.

	One machine is a 486 DX2/66 the other is a 586/133 machine. Both
	machines rebooted without warning message or else.

>Fix:
	
	No idea about that.
