[389-users] Fedora-DS 1.1 showing NSMMReplicationPlugin msgs, becomes unresponsive and dies

[Wolf Siedler]

Hi!

I am sorry for the vague subject but I don't know a better way to
describe my problem. I am still studying Fedora/389 Directory Server.
I am running a Fedora-DS (1.1) master on CentOS 5.4 which replicates to
several consumers (no master-master replication).

Today, the master suddenly stopped working. I can restart it, but it
never starts listeing on ports 389/636.
"service dirsrv status" claims after several minutes that the service is
dead.

When attempting a start by
/usr/lib/dirsrv/slapd-admin01/start-slapd -d 1
I get after a few seconds a seemingly endless loop of this message:

NSMMReplicationPlugin - agmt="cn=nagios" (rtbkk:389): Consumer failed to
replay change (uniqueid (null), CSN (null)): Bad parameter to an ldap
routine. Will retry later.

Usage of terms nagios and rtbkk point me indeed to one of our
replication agreements.

Can somebody explain what that means?

Is it possible that a replication agreement fails and then the server
attempts/repeats over and over until all resources are exhausted?

Can anybody advise how I could overcome this?

Needless to say, I would appreciate any advice/pointers (such incidents
always seem to happen at the wrong time).

Regards,
Wolf
