freeradius & sql server with high loads

[A.Dupont]

Hello,

I'm using freeradius 1.1.7 with sql server 2005, the problem is that I don't find all accounting in database, freeradius doesn't send ack for all accounting tickets (it sends 300 for 4000 tickets from 10 NAS), can you tell me what is the prob?
 here is a part of my radiusd.conf:

max_request_time = 120
max_requests = 10000
start_servers = 10
max_servers = 50
min_spare_servers = 10
max_spare_servers = 30
num_sql_socks = 40

I find these error in the radius.log :

Dropping conflicting packet from client myclient1  - ID: 45 due to unfinished request 1
.....
Info: rlm_sql (sql): There are no DB handles to use! skipped 0, tried to connect 0   (I use 40 handles )
....

CPU use: 100 %

can you help me plz?
thanks in advance
