Is this for pre-compiled package you downloaded or one you compiled? If you
complied it and its done on exactly same or similar machine and this can be
reproduced than we can investigate further (but I'd ask you to compile
nagios 3.2 as its the latest version). If its for binary package you
downloaded then for such support issues contact your distribution vendor.
