[Freeipa-users] ns-slapd hang/segfault

[Dan Scott]

Hi,

On my Fedora 15 FreeIPA server, I'm having some problems with
stability. The server appears to 'hang' and stops responding to LDAP
lookups. When I restart the dirsrv service, I get:

Dec 15 09:40:02 ohm kernel: [254566.011404] ns-slapd[28910]: segfault
at 17d ip 00007f00dbc0208c sp 00007fff929b7848 error 4 in
libc-2.14.so[7f00dbb87000+18f000]

and the /var/log/dirsrv/slapd-EXAMPLE-COM/errors contains

[15/Dec/2011:09:47:35 -0500] set_krb5_creds - Could not get initial
credentials for principal [ldap/example.com at EXAMPLE.COM] in keytab
[WRFILE:/etc/dirsrv/ds.keytab]: -1765328228 (Cannot contact any KDC
for requested realm)
[15/Dec/2011:09:47:35 -0500] slapd_ldap_sasl_interactive_bind - Error:

(Local error) (SASL(-1): generic failure: GSSAPI Error: Unspecified
GSS failure.  Minor code may provide more information (Credentials
cache file '/tmp/krb5cc_496' not found))

This is happening very frequently, I'm having to restart the dirsrv
process once an hour, otherwise people start complaining.

I experienced similar problems with FreeIPA 1, when I was using Fedora
14 and earlier, and had to regularly (also once per hour) restart the
dirsrv process. Could this be related?

I also noticed this:
https://bugzilla.redhat.com/show_bug.cgi?id=730387

There are updates in 'updates-testing' which I believe fix the above
issue, but I'm reluctant to install from a testing repo on my
production server, can anyone report any feedback on this?

Can anyone help me out?

Thanks,

Dan
