Hi listers
we are running 3 openldap servers:
one as provider with
openldap-servers-2.3.39-3.fc8
the other 2 as consumers with
openldap-servers-2.4.8-6.fc9.i386
the provider runs fedora 8, the consumers run fedora 9.
as i am aware that the slurpd mechanism for synchronization is no longer
supported in openldap-2.4.xxx, i tried to install syncrepl, all to no avail.
........
the actual situation is that as soon as i do a change in the provider,
the consumers immediatly get a segmentation fault and leave the bdb in
an unusable state. when i restart the consumers, they inform me about
the unusable db, refresh it and redo the pending syncrepl-request, which
again makes them do a segmentation-fault.
we use sleepycat dbs exclusively. the version on the consumers is
db4-4.6.21-5.fc9.i386
the config with regard to syncrepl is:
---- in the provider:
...
index entryCSN,entryUUID eq
....
modulepath /usr/lib/openldap/
moduleload syncprov.la
...
# syncrepl as a provider
overlay syncprov
#syncprov-checkpoint 100 10
syncprov-sessionlog 100
(i commented out syncproc-checkpoint after having read a corresponding
issue from a mailing-list)
---- in the consumers
...
index entryUUID,entryCSN eq
...
modulepath /usr/lib/openldap/
moduleload syncprov.la
...
# syncrepl as a consumer
syncrepl rid=1

when doing a change on the provider, the providers log is:

when the consumer tries do do a syncrepl the consumer's log is:

be_modify failed (16)
and then it fails with a Segmentation fault:
when running slapd -d7, i get:

Segmentation fault

i also thought, it might probably be a memory error and run the
memory-check for more than an hour: nothing was found.
what can i do else?
thank for all hints.
