The changelog for 6.7.17 says the following:
"The history file, which is a flat file for each submitting computer that stores information about all jobs completed on that computer is now rotated automatically. By default, the file will be rotated when it is more than 20MB and two backup files will be allowed (for a total of three history files with 60MB of data). This means that older history will be lost once it is rotated out. You can disable the history file rotation if you like, and you can change the number and size of the backup files. condor_ history has been updated to understand these backup history files."
I would like to diable file rotation but there doesn't seem to be an indication as to what parameters to change to do this. Is there documentation anywhere with regard to this?
