I have IC 4000 and it has been working fine with 600-700 users for past 4-5 months. But now we have about 1400 users and now almost every once in two weeks we have RAIDIUS authentication fails and need to restart/reboot the service to make it work. I am running 3.1 R8 . Is there any JTAC recommended version that has fixed this issue.
I keep getting the below message in the event log almost every 5 seconds.
