rlm_sql don't re-connect after mysql failure

[Jean Carlos Oliveira Guandalini]

Hi, I'm using freeradius-2.1.11 and i have problem with mysql
connection. If MySQL server goes down, the freeradius don't reconnect
until he be restarted.

logfile like this, but the mysql server is UP again:
rlm_sql_mysql: Starting connect to MySQL server for #0
rlm_sql: Connected new DB handle, #0
rlm_sql : failed after re-connect
*** this error repeats until I go restart freeradius

Thanks

Jean
