I noticed today that replication between a few of my four FDS machines (all MMR agreements going every which way) had failed with errors like this: [30/Aug/2007:00:02:04 -0500] NSMMReplicationPlugin - agmt="cn="Replication to chico (o=isp)"" (chico:389): Incremental protocol: event update_window_opened should not occur in state start_backoff [31/Aug/2007:00:03:59 -0500] NSMMReplicationPlugin - agmt="cn="Replication to chico (o=isp)"" (chico:389): Incremental protocol: event update_window_opened should not occur in state start_backoff [31/Aug/2007:07:35:59 -0500] NSMMReplicationPlugin - agmt="cn="Replication to chico (o=isp)"" (chico:389): Incremental update failed and requires administrator action I tried using mmr.pl to reinitialize the agreements, but that failed miserably and wiped all of the data from the database I was re-initializing. I got the following errors on the supplier: [31/Aug/2007:10:24:56 -0500] NSMMReplicationPlugin - Beginning total update of replica "agmt="cn="Replication to chico (o=isp)"" (chico:389)".

This looked really similar to an error I'd had before, in this thread: http://www.mail-archive.com/fedora-directory-users at redhat.com/msg04969.html I had eventually resolved that by dismantling all replication information, using db2ldif to import the database from the supplier to the consumer while the consumer was down, bringing the consumer back up, and reinitializing the replication agreements. This has not worked this time; I get the exact same errors. Anyone have any suggestions? Thanks! Chris St. Pierre Unix Systems Administrator Nebraska Wesleyan University
