Hi, I have the following 389 DS version deployed: 389-Directory/1.2.8.2 B2011.130.190 I have a 3 box multi-master replication setup in a ring: \ / \ / \ / \ / \ / … C ----- A ----- B ----- C ----- A … / \ / \ / \ / \ / \ The replication agreements for “A” and “C” and for “B” and “C” work fine, but I have an issue for the agreements for the “A” and “B” connection. I see the following in the errors file: Server A: [19/Jul/2012:07:28:50 -0300] NSMMReplicationPlugin - conn=7835 op=160267 repl="o=base": Begin incremental protocol [19/Jul/2012:07:28:50 -0300] - csngen_adjust_time: gen state before 5007e1610000:1342693727:0:2 [19/Jul/2012:07:28:50 -0300] - _csngen_adjust_local_time: gen state before 5007e1610000:1342693727:0:2 [19/Jul/2012:07:28:50 -0300] - _csngen_adjust_local_time: gen state after 5007e1640000:1342693730:0:2 [19/Jul/2012:07:28:50 -0300] NSMMReplicationPlugin - conn=7835 op=160267 repl="o=BASE": Replica in use locking_purl=conn=7831 id=3 [19/Jul/2012:07:28:50 -0300] NSMMReplicationPlugin - conn=7835 op=160267 replica="o=BASE": Unable to acquire replica: error: replica busy locked by conn=7831 id=3 for incremental update [19/Jul/2012:07:28:50 -0300] NSMMReplicationPlugin - conn=7835 op=160267 repl="o=umc": StartNSDS90ReplicationRequest: response=1 rc=0 This kind of error is logged in an interval of about 1 second, where the local_time differs 5007e1610000:1342693727:0:2 Server B: [19/Jul/2012:13:28:48 -0300] NSMMReplicationPlugin - agmt="cn=A-to-B" (A:389): Unable to receive the response for a startReplication extended operation to consumer (Timed out).

I did see the Bug 571677 (https://bugzilla.redhat.com/show_bug.cgi?id=571677), but there was no deletion of a replicaconflict object. Did anybody encounter this kind of issue? The next question would be: How to recover the MMR environment. Thanks, -Reinhard |
