BugId's fixed with this patch: 1038930, 1038916

Architectures for which this patch is available: sun4 sun4c Sun3 and Sun3x

Obsoleted by: 4.1.1 

Problem Description:

	Various lockd core dumps and client process going into disk waits
        have been addressed by this patch.

	i) Fixed problem with running out of file descriptors and
	getting RPC TIMEOUT errors, seen when running large number
	of diskless clients.

	ii) Fixed problem where fd and fd structure was not released
	when doing test lock, eventually running out of file 
	descriptors. This problem would occur when running WP and
	quitting out of the window.

	iii) Fixed problem where rpc.lockd core dumps after a large
	amount of time when running "fame" application.

	iv) Fixed problem where restarting lockd on a client results
	in the server not being able to communicate with the new lockd
	as it has an old client handle that is associated with a now
	invalid port number.

	v) Fixed problem where upgrade from a read lock to a write lock 
	is allowed when remote read locks are outstanding.


Special Instructions:

	If patch 100075-04 has been installed than only the new rpc.lockd
