buffered-sql question

Greetings, I have set up the buffered-sql server to handle importing accounting packets from my backup radius once a day. I transfer the detail file (via ftp) from the backup server to the newer server and put it in place for the buffered-sql to use it, but it doesn't seem to read the file. I though, from the description in the documentation, it would run ever X seconds. I've set mine to 60 seconds for testing. Am I doing something wrong? wm
