Hello,
We're having the following authentication scenario for Wimax User
Authentication :
ASN -- EAP/TTLS ---> 2 freeradius used as proxy --> 2 freeradius home
server.
AAA is fine when both home servers are up,but when one of them or both
of them are dead, we're having the following logs on the proxy :
rad_recv: Access-Request packet from host a.b.c.D port 10008, id=117,
length=406
Sending duplicate proxied request to home server a.b.c.d port 1812 - ID: 36
Sending Access-Request of id 36 to a.b.c.d port 1812

Waking up in 21.0 seconds.
WARNING: Internal sanity check failed in event handler for request 6:
Discarding the request!
Segmentation fault
And then the proxy radius dies.
This happens each time at the fifth try while trying to send the request
to a dead home server.
Regular logs gives that
Nov 18 01:37:46 vma-prdaut-08 radiusd[11028]: Marking home server
a.b.c.d port 1812 as zombie (it looks like it is dead).
I know I should give a gdb trace to help, but since this is production
server, it might take some times to give the trace.
Do you have any idea to what it could be related ?
Environment is the following :
FreeBSD 8.0/ Freeradius 2.1.10 compiled on threaded perl for snmp script
use.
Thanks
Thomas
