In some environments, there can be multiple instances of a process running, such as DAS Binary, the Sentinel Control Center, or Sentinel Data Manager. If so, the first instance’s log files are named as described above (For example, das_binary0.0.log). The second instance will substitute a 1 for the first 0 in the log file name (For example, das_binary1.0.log).
If other processes have log files indicating that more than one instance is running, that could indicate a system problem.
