I recently upgraded our freeradius servers to 2.1.8 and over the past
month it has died on one of the servers two times (spaced about two
weeks apart I think). So fairly infrequently.
A bit of background, We use this server predominantly to proxy
requests. Every day for about 15 minutes, the two main home servers we
proxy to stop responding (they are doing backups or maintenance during
this time) so for those 15 minutes our clients (LNS/NAS) would be
sending a very large number of accounting interim packets and some
stop packets and would be resending these while the home servers are
down.
Some relevant proxy home server settings we currently use for the main
home servers we proxy to:
response_window = 14
zombie_period = 40
status_check = status-server
check_interval = 30
num_answers_to_alive = 3
The times that freeradius has died has been near the end of the 15
minutes of the home servers downtime.
The last time this happened, I noticed logs in the attached file. Ones
that sound relevant as follows:

port 1646 as zombie (it looks like it is dead).

That last one is where it dies I think.
That last error seems a bit similar (but a bit different) to the
following thread:

That one was found to be a bug and was fixed - I don't know if my case
is a bug though.
Another thread that sounds useful for this is:

I don't currently use the robust proxy accounting that that thread
suggests. I expect that would probably work around the issue of
freeradius crashing in this case and I will give that a go. Just
posting this to let you know that it _might_ be a bug and to ask for
advice about whether you think this is a bug or not, and if I should
follow up on that, or if you think it is just my configuration that
needs some changes and what areas I should concentrate on if that is
the case?
