I'm in the middle of instrumenting the code to find out what is going on. I've attached an edited log show httpd coming up during boot and failing followed by systemctl restart httpd.service after boot. The attached log is the stdout from systemd starting httpd.service. I have also made a change to the config to use port _default_:8080 for the public facing server and 127.0.0.1:80 for the internal facing server. With that change httpd will not start up. You can see the failure log: [823] info: [Tue Jul 12 17:51:43 2011] [error] (EAI 9)Address family for hostname not supported: Could not resolve host name 127.0.0.1 -- ignoring! The lines with QQQ on them are my instrumentation. I've patched httpd-2.2.17/server/vhost.c and apr-1.4.5/network_io/unix/sockaddr.c. The instrumentation seems to show me that the httpd and apr code is fine. My next step is to instument glibc getaddrinfo to find out why it returns EAI_ADDRFAMILY. Have you seen issues with getaddrinfo elsewhere? We are using kernel-PAE-2.6.38.8-93.fc15.i686 and glibc-2.14-2.i686 I can provide the patches and full config if that is useful. Barry
