When there is a replication process running in the background, starting an import process will cause a conflict.
In order to fix this conflict, we suggest that you turn off the replication processes, wait for replication to finish, and run the import process.
In order to turn off the replication process go to:
[Admin tab] ? [Repositories] ?[A repository with replication] ? [Edit] ? [Replication tab] ? [uncheck ‘Enabled].
In order to turn off replication process on all the repositories go to:
[Admin tab] ? [Advanced] ? [Config Descriptor] ? [search for ‘localReplication’ and ‘remoteReplication’ tags] ? [set ‘enabled’ to false on all of the repositories] ? [save]
