1. What is the reason of such FreeRadius behavior? What must I do?
It looks like a slow database problem.
2. Why load of server during #radiusd -X is lover then during #radiusd ?
radius -X starts the server in single-threaded mode, and the database server receives one request at a time. In normal mode, FreeRADIUS sends multiple requests simultaneously to the database server, and the database becomes too slow to answer to all the requests. At some point you get the message "There are no DB handles to use!"
3.How must I start FreeRadius to make many processes (not threads), maybe it help me to decrease the load of server and to increase the speed of packets handling
I'd suggest to find out why the database is slow (perhaps there is no index). On the FreeRADIUS side, try to adjust the value of the num_sql_socks option in sql.conf. -- Nicolas Baradakis
