Hi,
I am using freeradius 2.0.4 (official deb package) - unfortunately, this is a very old server with Debian 5.
It's a VMware virtual machine with 3 GB ram and 4 vCPU.
I noticed that freeradius take very long time to start.
Here is strace output of starting pid:
# strace -p 3889

Since I notice a very high load on this server (freeradius seems to be to root cause, according to top), I'm looking for some help.
Thank you
