Pls help: missing Stop accounting packets

Hi all,

I'm using FreeRadius 2.1.3 on 2 Linux machines with accounting data stored in both radacct file and MySQL database.  Recently we found that some 'aged' records have AcctStopTime = NULL.    Seems Stop accounting packet for these records are not received.  The problem is consistent in both cases - such Stop packets didn't recorded in radacct file and MySQL database.     I've no idea whether the stop packet sent to radius server was not recorded, or if  stop packet was not sent from AP.   As we're using Aruba AP, I wonder if Stop packet will be missed under particular situation, e.g. session timeout, disconnect without proper logout, etc., or if I configured our radius servers incorrectly so that some stop packets are not received or recorded.   Meanwhile, I'd also like to know if there is any solution to clean up such orphan records if they can't be avoided.

Would anyone please help?  Sorry for the newbie question.  Thanks a lot.

Best Regards,
