Dear List. I have a Freeradius 2 installed, using a MySQL database to store all accounting data. Usually It works fine, but now I can see that the count of AcctSessionTime is being wrong calculated in SOME cases, not all caases. Check it out these records. "AcctStartTime";"AcctStopTime";"AcctSessionTime" "2016-01-20 18:08:54";"2016-01-20 18:22:10";"337444" "2016-01-20 18:13:26";"2016-01-20 18:22:25";"337172" ""2016-01-20 18:15:24";"2016-01-20 18:22:10";"337054" "2016-01-20 18:15:44";"2016-01-20 18:22:10";"337034" "2016-01-20 18:16:00";"2016-01-20 18:22:10";"337018" "2016-01-20 18:16:34";"2016-01-20 18:22:10";"336984" As you can see each session takes less to 15 minutes (900 seconds) But its calculated about 93 hours (224800 second). What Can I do? My statistics are being damaged!! Regards -- *C. Andrés Gómez R.*
