>Environment:
System: NetBSD 5.99.29 2010-05-25 06:00 UTC
Architecture: i386
Machine: i386
>Description:

	My syslog is filling up with the following messages while ssh
	or ftp are used to connect to remote sites:

WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 19374 command ssh)

WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)
WARNING: defaulted mmap() share type to MAP_PRIVATE (pid 8870 command ftp)

	A ssh session only cause one line but ssh is producing 6 or 7
	lines for each session.

>How-To-Repeat:
	Use a kernel with DEBUG enabled and watch the syslog messages
	while you execute the following commands:
	* ssh
	ssh ftp.netbsd.org
	* ftp
	ftp ftp://ftp.netbsd.org/
