Hi Karthik, I used to have the same problem in 2 different cases: - When Freeradius was installed on Redhat 9, it used to hang every 3 or 4 days as well but you're on Redhat Ent3 so you should be fine - When the connection to the MySQL server was dropping Are you sure your connection to AD is reliable? David ----- Am running freeradius ver 1.1.1. My connection to AD is reliable, but today i remembered before this issue araised recently i rebooted the domain controller. Not sure if this is causing the issue.
