Hello!
The maximum size of the MDS logfiles can be altered by the mds.ini parameter "MDM Log Watermark":
The value is the maximum size (in bytes) an MDM log file can grow to before a new log file is started. Value must be greater than 1048576 (1 MB). Default is 2097152 (2 MB).
You can also configure the maximum number of log files, with the "Max Number of Log Files" parameter:
The value is the maximum number of log files to keep in the MDS \log dir. After this number is reached, the oldest log file is deleted. (If set to 0, MDS still keeps one log file). Default value is 20.
BR,
Carlos
