Error description
The command QUERY REPLICATION may report an incorrect "End Time" for an already ended replication process if the following conditions are met : - Two or more replication processes are started at the exact same time, i.e. in the same second. - One replication process ends before the other. A QUERY REPLICATION done when the first process has finished, shows the correct "End Time" value for this process. Later when the other process(es) finishes, the "End Time" value for all the processes that have the same "Start Time" are updated using the last process "End Time" value. Tivoli Storage Manager Versions Affected: All platforms 6.3 Customer/L2 Diagnostics : - Two processes are started from a script in the same second: 2014-01-22 11:00:22 ANR0984I Process 1914 for Replicate Node started in the FOREGROUND at 11:00:22.

Local fix
- Do not use a script to start concurrent replication processes to avoid having them started with exact the same "Start Time"
