Thanks Jan for your help. There is no portmapper running on the platform
and portmap was not built on the platform. But I have another similar
platform that running Busybox 1.00 and does not have portmapper running
either. According my search from internet, portmapper is not needed if
use mount with -o nolock option.

Regards,

Strong
