I found that when running radius -x to the console I see lines like the
following
WARNING: Unresponsive child (id 3074419616) for request 8978
I don't know what they mean. I see lines like
Dropping conflicting packet from client Bogus:2377 - ID: 195 due to
unfinished request 8978
above the Warning line but don't see where the original request is and don't
know if it matter?
I am not sure how to use strace I ran it on the pid of the radius server but
don't know what to make of its output.
Below is a small excerpt of the output
