When a Data Replication InitialSync, Extractor, or Applier task log file exceeds its specified maximum size or the time period for switching log files, the task log redirects its output to a new task log file. This error occurs when Data Replication cannot switch to the new log file for a number of possible reasons, including low disk space, insufficient user privileges, or any other issue that prevents the new log file from being created. When this error occurs, Data Replication continues to write the output to the current task log file.
