Won't be much help without a core dump :(

The error looks like you haven't set "ulimit -c 0" before starting
FreeRADIUS?

Otherwise if it is a permissions thing and on Linux you could set a
core pattern so it writes to, e.g. /tmp:

# echo "/tmp/core.%e.%p" > /proc/sys/kernel/core_pattern

Nothing to worry about. There were clients in the middle of EAP
transactions when the server stopped. They keep trying to
retransmit to continue their auth.

When the server starts back up again it gets a load of packets
from the middle of these old EAP transactions that it doesn't know
about, so rightly complains that there is no EAP state.

After a short while the clients time out and start again so the
errors go away.

But, yes, it can be a bit disconcerting when you restart a server
and initially see a load of errors.
