Have a new list option: Auto-cleanup. When the logs of a list are bigger than a specified size, a cleanup routine runs and erase the older logs, until enough disk space is free. Then, resume the normal operation. Or, clean up the logs of a list when they are older than a specified date. The last solution could cause of course a disk-full problem if the list has big traffic, but with the proper use of date limit, the problem can be solved. Theodore Soldatos.
