Seg fault during synrepl update with 2.3.4

[David Harrison <david.harrison@sensorynetworks.com>]

Hi all,

I have a syncrepl setup going between a new slapd using 2.3.4 (since
apparently the replication under 2.2 is known to be unreliable) and my
existing slapd which runs 2.2.23.
The 2.3.4 is the consumer, and the 2.2.23 is the provider.

The backend is bdb, using db 4.2

I start with a completely empty database on the consumer side, start the
consumer slapd instance and it successfully sucks down all the entries,
and can properly respond to queries.

However, when I then change an entry in the provider directory, the
consumer seg faults when it tries to bring down the change.
The fault occurs irrespective of whether I am using TLS or not.

Cheers for any help,
Dave


This is my syncrepl config on the consumer side :

syncrepl rid=100
        provider=ldap://ldap.mydomain.com
        type=refreshOnly
        interval=00:00:00:20
        searchbase="dc=internal,dc=mydomain,dc=com"

filter="(&(|(objectClass=Employee)(objectClass=MailGroup)(objectClass=
EMailAlias)))"
        scope=sub

attrs="cn,sn,primaryEmail,emailAlias,uid,mail,givenName,displayName,tele
phoneNumber,department,xmozillanickname,recipientEMail,groupEMail,emailAlias,des
cription"
        schemachecking=off
        bindmethod=simple
        binddn="cn=sync,dc=internal,dc=mydomain,dc=com"
        credentials="foo"
