Resolution:
This error indicates that these jobs were corrupted in the file system and could not be read back into memory by BW. These jobs could have been corrupted either by BW terminating abnormally when the jobs were being written to or being read from or by any other external influences on the file system. For example, network problems or files are locked by other processes. Check in Admin GUI if that shows recoverable processes. If yes, manually process them. Check if the directory to store the check-pointed jobs is valid and not corrupted. If the file is present, try restarting the application.
