Nov 24 03:44:28 [10189]: logout: entry for NAS 213.189.233.100 port 5 has wrong 
ID (expected a found b)

how radiusd do logout of user (i mean clear user from radwtmp)
1. NAS send 'stop' request like:
user_name aza
port = 2
session_id = ab

radiusd should find user 'aza' AND 'port=2' AND 'session_id = ab'
and clear it from radwtmp (and from mysql by acct_stop_query)

i guess my NAS (3Com 1500 RAS) sends illegal 'port' and 'session_id' when user 
logout.. :(
but it 100% right sends his user_name.

I removed session_id from my sqlserver file:
---
# Query to be used on session end
acct_stop_query      UPDATE calls \
                     SET status=%C{Acct-Status-Type},\
                         acct_session_time=%C{Acct-Session-Time},\
                         acct_input_octets=%C{Acct-Input-Octets},\
                         acct_output_octets=%C{Acct-Output-Octets},\
                         connect_term_reason=%C{Acct-Terminate-Cause} \
                     WHERE user_name='%C{User-Name}' \
                       AND status = 1
---
this action will apply on mysql only, right?

so what should i do with radwtmp? 

Sorry for my english.

Thank you.
