Logs can pile up and often take up disk space which may result in you having to increase disk size. To keep this from happening, you may delete your logs to free up some space. This can be done manually, but you may also set this up in a way where the logs auto-delete after a set time frame, say 30 days, 60 days, etc.
To set up auto-delete for your logs after a certain time period, you may use log rotate as described here: Setting up Log Rotation
It seems that Access Server saves the logs in log.db? Is the configuration recognized as.conf?
You would need to apply log rotate configuration in as.conf file followed by the crontab and script procedure to automate the removal of old log files.
