From the FAQ posting:

16. Why do I get the error "ps: unlink() error" every once in a while?

	This error is caused by the ps program being unable to remove
	the /etc/ps_data file.  This is usually a permissions problem
	on /etc or /bin/ps.  The files and/or directories should
	be set with the following modes:

	drwxrwxr-x  20 root     sys         3968 Apr 29 08:36 /etc
	-r-xr-sr-x   1 root     sys        21472 May 22  1989 /bin/ps

	In english:
		/bin/ps must be mode 2xxx (set-gid)
		/bin/ps must have the same group as /etc (usually sys)
		/etc must be group writable
