[Freeipa-users] 389 DS server closing connection after upgrade from Fedora 12 to 13

[tomasz.napierala at allegro.pl]

Hi,

Although I was very happy with FreeIPA on F12, due to compliance issues I had to upgrade our master server from F12 to F13. I tried several methods, and only yum upgrade was semi succesful.
After upgrade 389 seems to be running fine, with one exception: it stops responding queries after few minutes. All daemons are running fine:

But every connection lokks like this:

[root at ipa ~]# telnet localhost 389
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.
[root at ipa ~]# telnet localhost 636
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

Connection is closed immediately. 
[root at ipa-pci ~]# tail /var/log/dirsrv/slapd-QXLPCI/errors

        ipa-pci.dc3:636 (/etc/dirsrv/slapd-QXLPCI)

I see nothing in the logs:

[21/Feb/2011:00:17:27 +0100] - 389-Directory/1.2.7.5 B2010.350.1724 starting up

[21/Feb/2011:00:18:34 +0100] - conn=51 received a non-LDAP message (tag 0xd, expected 0x30)

Dirserver restart helps for few munites.
Looks quite serious and I really have no more ideas how to debug it. 
My setup:
389-ds-base-1.2.7.5-1.fc13.x86_64
ipa-python-1.2.2-4.fc13.x86_64
ipa-client-1.2.2-4.fc13.x86_64
ipa-admintools-1.2.2-4.fc13.x86_64
ipa-server-selinux-1.2.2-4.fc13.x86_64
ipa-server-1.2.2-4.fc13.x86_64

[root at ipa ~]# grep 389 /var/log/yum.log
Feb 20 15:35:35 Updated: 389-ds-base-1.2.6.1-2.fc12.x86_64
Feb 20 23:47:19 Updated: 389-ds-base-1.2.7.5-1.fc13.x86_64

Any one have an idea what could be the reason?
