I have been using freeradius for several years but in the last few months have seen a problem with the cpu usage. TOP almost always shows radius with > 100% CPU much of the time it is at 300%. The load average runs up to 32 at times as well. This corresponds with the max_servers. I am using a mysql database on the same box and it looks to be behaving and queries to it are fast. The box is dual 2.8 xeon with 2 GB ram. Anyone have a idea what would cause this?
