[Serusers] flatstore log rotation question

Hi All. I'm using ser-0.8.99-dev10 with flatstore.so. Can anyone tell me how to determine when a flatstore log file will no longer be written to? The reason I ask is that I need to move these flatstore files periodically to my billing system and I need to make sure that I don't interfere with flatstore when doing so. I also need to make sure I remove CDRs that I've already sent to my billing server. So for example, I want to grab all CDRs every hour - on the hour. So I would copy the previous hour's call records to my billing server. Then I would delete these calls from the ser flatstore directory to avoid getting duplicate CDRs in my billing system. How can I achieve this? I'm very unclear on how flatstore.so decides to rotate logs. Regards, Paul _______________________________ Do you Yahoo!?
