Hi, All, My first time posting here. Correct me if the content or category is wrong. I am using freeradius-1.1.8 as well as 1.1.4, each time I got log message at /usr/local/var/log/radius/radius.log Dropping conflicting packet from client xxxxx:14991 - ID: 126 due to unfinished request 13945 (the figures might change) Then radiusd stopped and the linux showed top 9x% utilization. I have to kill -9 PID and restart it again. It would run for a while then come to above problem again then stop. I could not install freeradius-2.xxx because I am not using up-to-date fedora, my uname -r is currently as 2.4.18-14, it can not compile the version 2xxx of freeradius. Coud somebody please give me any help on this issue? Thanks a lot. George
