Make sure that you only have IPv4 addresses in your /etc/resolv.conf (from the bug that tru posted) |
 |
indeed, with only IPv4 resolvers sendmail will start. As soon as even one of them is an IPv6 address, the segfault occurs. using IPv4 only for now |
|
|
When using brackets, there is no problem. [root@shell ~]# cat /etc/resolv.conf ; generated by /sbin/dhclient-script search domain.tld nameserver 11.22.33.44 nameserver 55.66.77.88 nameserver [2a01:1:b::c53] nameserver [2a01:1:a::c53] |

when using brackets, there is no problem as in the fact that nothing crashes; however, if you have _ONLY_ IPv6 resolver addresses, you can't resolve anything. You will note that if you remove your 11.22.33.44 and 55.66.77.88 IP addresses from your resolv.conf, the system no longer can resolve anything. |

Commenting out the ipv6 nameservers using an ipv6 address helps. Thanks. |

https://rhn.redhat.com/errata/RHSA-2012-1098.html * A programming error caused an internal array of nameservers to be only partially initialized when the /etc/resolv.conf file contained IPv6 nameservers. Depending on the contents of a nearby structure, this could cause certain applications to terminate unexpectedly with a segmentation fault. The programming error has been fixed, which restores proper behavior with IPv6 nameservers listed in the /etc/resolv.conf file. (BZ#837026) |

I confirm that updating glibc-2.12-1.80.el6_3.3.i686 has fixed the issue |
|
|
I activated the resolv.conf ipv6 nameservers after updating glibc and I can confirm that my issue is resolved too. It is working fine now. |

marking as solved as per reporters feedback |
