Hi Currently I have a NAS device in a hosting centre and the SQL Server with the auth and accounting data in another data centre. There's a 1G link between the two and the ping time between them is ~9ms In time I am hoping to move the SQL server closer to the main NAS, but for now would the best option be to place the FR server closer to the NAS (with a higher latency to the SQL server) OR place the FR serve closer to the SQL box ? Currently I have the FR server near the NAS and the SQL server remote - but wanted to check this was 'sensible' Moving to FR 3 (from an old server with 2.12) I am seeing more log messages like: Tue Mar 15 10:26:24 2016 : Error: (27774) Ignoring duplicate packet from client mer-fire11 port 3799 - ID: 181 due to unfinished request in component post-auth module sql and Tue Mar 15 10:27:12 2016 : Error: (27785) Discarding duplicate request from client mer-fire11 port 3799 - ID: 158 due to delayed response I have my DBA checking the radius server to see if anything can be tuned here - but I wanted to ensure we had the best possible setup here - We are using MSSQL as the backend here - via UnixODBC/freetds Thanks in advance Richard
