To determine the cause of replication failure using a faster replication mode, suspend replication before Replication Server reverts to the continuous log-order replication mode.
You can then analyze the Replication Server log file or dump queue for information about the failed transactions to determine the reasons for the failure to apply transactions in the faster replication modes such as high-volume adaptive replication (HVAR), real-time loading (RTL), dynamic SQL, parallel DSI, or DSI bulk copy-in.
See Unable to Continue Replication in a Faster Mode in the Replication Server Troubleshooting Guide.
