"Dropping conflicting packet" and "Rejecting request"

[Takeshi Yoshida]

I am moving FreeRadius(1.1.0 Sparc Solaris9) by the following compositions. 
(Target is "* Proxy *")

 ------------                       ---------------
 | Radius-1 |-->                 -->| HomeRadius1 |---RDB
 ------------  |   -----------   |  ---------------
               |-->|* Proxy *|-->|
 ------------  |   -----------   |  ---------------
 | Radius-2 |-->                 -->| HomeRadius2 |---RDB
 ------------                       ---------------

The role of this server is only a Proxy server. 
The occasionally following errors are output by "radius.log"


  Wed Feb 22 11:53:38 2006 : Error: Dropping conflicting packet from client Radus-1:1039 - ID: 246 due to unfinished request 7101301

       and

  Wed Feb 22 11:53:38 2006 : Error: Rejecting request 7101299 due to lack of any response from home server Radius-1:1039


Why are these messages output?

The number of requests that *Proxy* receive is AUTH=10 and ACCT=15 in about one second. 

It is a setting as follows. 


    --- radiusd.conf ---
    max_request_time = 12
    delete_blocked_requests = no
    cleanup_delay = 6
    max_requests = 20480
    hostname_lookups = no
    reject_delay = 3
    proxy_requests  = yes

    --- proxy.conf ---
    proxy server {
        synchronous = no
        retry_delay = 0
        retry_count = 0
        dead_time = 60
        default_fallback = yes
        post_proxy_authorize = no
    }


When the examination on which I put the load is done, this error is fully output. 
However, it is output when the load is low. 

There is always one kind of UDP transmission Port of "Radius-1" and "Radius-2". 
(It is not unique at each request. )

Because this server is being operated, it is not possible to do in debug mode. 

Please give something a good idea to me. 
I'm sorry in strange English. 
My best regards.
