I have nagios 1.2 installed and apache 2.0.54-r31. When visiting the nagios status.cgi (or any other cgi) apache workers crash (but apache itself keeps working) with following error message: *** glibc detected *** corrupted double-linked list: 0x00002aaaac479a38 *** *** glibc detected *** corrupted double-linked list: 0x00002aaaac479a38 *** *** glibc detected *** corrupted double-linked list: 0x00002aaaac479a38 *** *** glibc detected *** corrupted double-linked list: 0x00002aaaac479a38 *** [Thu Oct 27 09:09:03 2005] [notice] child pid 12170 exit signal Aborted (6) [Thu Oct 27 09:09:03 2005] [notice] child pid 12171 exit signal Aborted (6) [Thu Oct 27 09:09:03 2005] [notice] child pid 12172 exit signal Aborted (6) [Thu Oct 27 09:09:03 2005] [notice] child pid 12269 exit signal Aborted (6) Reproducible: Always Steps to Reproduce: 1. 2. 3.

I just found out that this happens due to a combination of mod_ldapauth and an LDAP-server that was down. You still get the authentication request in the browser but apache then dies ... So it looks like mod_ldap is to be blamed here. Works fine after starting the ldap server again ...
User worked the issue out.
