Hi,

What are the best options to configure sqlite3 sql with freeradius?

i'm having some lock errors followed by  "ERROR: Hit reconnection limit"

I tried to set the pool to only 1 server, since its a file db, but them 
i got the error "max connections2 when connecting two users at the same 
time.


Right now i use:
....
thread pool {
     start_servers = 5
     max_servers = 25
     min_spare_servers = 3
     max_spare_servers = 10
     max_requests_per_server = 1024
     auto_limit_acct = yes
}


sql {
     driver = "rlm_sql_sqlite"
     sqlite {
         filename = "radius.db"
         busy_timeout = 200
     }
     dialect = "sqlite"
     delete_stale_sessions = yes
     pool {
         start = ${thread[pool].start_servers}
         min = ${thread[pool].min_spare_servers}
         max = ${thread[pool].max_servers}
         spare = ${thread[pool].max_spare_servers}
         uses = 0
         retry_delay = 30
         lifetime = 0
         idle_timeout = 60
     }
...


The errors  are:
