Bug 110598 – Apache worker crash when visiting nagios status.cgi (combined with ldap authentication and a missing ldap server)

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Christian Theune 2005-10-27 00:14:41 UTC]

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 ***

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 ...
