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. <div class="gmail_quote">On Mon, Nov 16, 2009 at 1:51 AM, Assaf Flatto <<a href="mailto:assaf.flatto@ssp-intl.com">assaf.flatto@ssp-intl.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hello . I am new to the nagios-devel list , and I am sorry if I am asking about things already discussed , but I am having an issue that is giving me grief and could not get a solution on any other place . I tried the nagios users list and googled this several times , but the issue is repeating . I have nagios 3.0.6 from source complied on SLES 10.2 (i586) with glibc-2.4-31.58 ,apache2-2.2.3-16.19 and the kernel is 2.6.16.60-0.33-bigsmp .
