One of the objects being replicated is a large group containing about 21000

for about 6 seconds or so, and at that point it times out, responding with the

[05/May/2014:15:33:36 +0100] NSMMReplicationPlugin - agmt="cn=Agreement

serverc is in Johannesburg, on a far slower connection than servera in DFW and
serverb in London. It appears there is some kind of timeout that kicks in and
causes the replication to suddenly be abandoned without warning.
Does anyone know what timeout is used during replication and how you set this
timeout?
Not ottomh but this will be covered in the documentation :
https://access.redhat.com/site/documentation/en-US/Red_Hat_Directory_Server/8.2/html/Configuration_and_Command-Line_Tool_Reference/Core_Server_Configuration_Reference.html#cnconfig
I'd be astonished if the default timeout is anything close to as short
as 6 seconds though.
The setting might be "nsslapd-outbound-ldap-io-timeout", but the docs
say the default is 5 minutes.
fwiw in more than 15 years working on the DS, I can't recall ever
hearing of a problem caused by the timeout on replication connections
being too _short_, but I suppose there's a first time for everything...
