(ITS#7274) delta-syncrepl MMR infinite loop - like issue?

[Francesco Malvezzi <francesco.malvezzi@unimore.it>]

During the setup of a mirror mode cluster, I enabled the syncprov after
building the mirror.

So maybe I run into ITS#7274:
http://www.openldap.org/its/index.cgi/Documentation?id=7274;selectid=7274;statetype=-1

delta-syncrepl fails with:
1) ABANDON log messages on provider;
2) matching "delta-sync lost" log messages on consumer.

Do I understand correctly: provider needs contextCSN value for SID=0 in
order to have delta-syncrepl working?

Does the following query confirm the lack of the contextCSN value for SID=0?

ldapsearch -ZZ -h ldap.example.org -LLL -x -s base -b dc=example,dc=org
contextCSN
dn: dc=example,dc=org
contextCSN: 20140925113354.230424Z#000000#001#000000
contextCSN: 20140925113307.523494Z#000000#002#000000

If the mirror mode cluster is in production, do I have any hope to setup
delta-syncrepl?

Thank you,

Francesco
