[Fedora-directory-users] slapd crash on replicate attempt

Hi- This morning a multi-master pair that has been running since Nov. 5 crashed. There is only one clue, in the error log of one of the directories: NSMMReplicationPlugin - agmt="cn=auth_ldap2 to auth_ldap1" (ldap:389): Unable to receive the response for a startReplication extended operation to consumer (Can't contact LDAP server). Will retry later. That appears to be the last thing either process said before they both gave up, almost simultaneously. Can anyone help me understand what happened? It looks like the replication agreements survived; at least, in the replication configuration section of each directory's console, there is a message with a current time saying "Incremental update succeeded." Thanks! Justin
