When a slave node is launched, Jenkins logs this in a file called "slave-nodeName.log". For each new launch (or launch attempt) after being disconnected, this log file is rotated. Ten rotated log files (log.1 to log.10) are kept. Once all of these are present, each new launch (attempt) will overwrite the log of the directly preceding attempt. No more rotation takes place; the files .1 to .10 remain as they were.
