It came out after a lot of problems with the amd automounter which rendered a server completeley useless and the very interesting issue is, that the loopback interface, lo0, has IPv6 configured, but it doesn't have IPv4 configured anymore. After a recompilation of the kernel on the 31.12.2012 and a reboot, the box is not responsive anymore (it a remote box I reach not before 07th Jan). NAGIOS is still reporting ICMP ping is good, but every other service is down. On another server I do not face this problem - or have faced that problem and I use the very same OS revisions on most of the CURRENT boxes. But all machines started suffering from some amd automounter issue before the problem got serious. This is strange ... oh --------------enig7057F6D1E16ABC969076556D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQEcBAEBAgAGBQJQ42m6AAoJEOgBcD7A/5N85LoIAI3dbxqkN66HGdappKrMcUdS dbKUV0eUmKeO3uuPHVdeoV6eQMDRvgJAKPdCNPRBCiBuTAFxCHqc+xLP0mw2gFRR AzUbwjBRATxG30jfqZq/nOE/xn2N4a40aQtbfU97oQuReWZL122L5pvcEK93QlOJ o48iVVH3qP6tAAST0AAl+oQ7kjaSM07jFAKAsabNLQJOR6WtkUF/XnIp63MJd+zh ilRywYu09Fc8b05naMRPBJuDri6QV0i6qW6fzT3nkHZEDg/4c1iSc5v3Q8+5XJxL zoeDuc7/zGo9KR50GSkpdIsTFqAtFYpUBCVMQaQaNdnsEpkuiUxlWuAkkTZrOrA= =NrNq -----END PGP SIGNATURE----- --------------enig7057F6D1E16ABC969076556D--
