-25019: Error opening server log file '<log_file_name>' (<error_text>). Opened temporary log file '<temp_log_file_name>' 

Explanation:

Attempts to open the log file of the Loader failed. This may have been caused by another Loader already running on the same computer. If more than one Loader is started on one computer at the same time, only one is able access the log file at a time because log files can only be opened exclusively.

A temporary log file is opened so that the Loader can still process the statements. The name of the log is stated in the message.
