1.7.1 krb5kdc crash on Enterprise Linux version 5 u4 x86_64

[Kevin Longfellow]

Hi,

We are testing a Kerberos version 1.7.1 environment on EL5u4 and the KDC crashed with the below in /var/log/messages:

Mar 25 20:26:16 dadvil0122 kernel: krb5kdc[4124]: segfault at 0000000000000000 rip 0000003eeea7bcb4 rsp 00007fffe1f90c58 error 4

1.7.1 was built from source with ldap and we are using ldap as the back end.  Looking at krb5kdc.log there was an AS_REQ about 26 minutes prior to the crash.  Other than the message above, we are not sure what steps we should take to debug this issue?  The krb5kdc was running for about 10 days when it crashed.

Kerberos was built with this command:

./configure --prefix=/opt/krb5_local/1.7.1 --with-ldap --sysconfdir=/opt/krb5_local/etc

Any help with this issue is appreciated.

Thanks,
Kevin
