rlm_sql logging results

[Laura Steynes]

Hello,

I am new-ish to freeradius, sort of stumped with resolving this -

When a user goes to log on the logs start with

Mon Apr 11 02:41:33 2016 : Info: rlm_sql (sql): Closing connection (131):
Hit idle_timeout, was idle for 3600 seconds
Mon Apr 11 02:41:33 2016 : Warning: rlm_sql (sql): You probably need to
lower "min"
Mon Apr 11 02:41:33 2016 : Info: rlm_sql (sql): Closing connection (132):
Hit idle_timeout, was idle for 3600 seconds
Mon Apr 11 02:41:33 2016 : Info: rlm_sql (sql): Opening additional
connection (133), 1 of 32 pending slots used
Mon Apr 11 02:41:33 2016 : Info: rlm_sql (sql): 0 of 1 connections in use.
Need more spares
Mon Apr 11 02:41:33 2016 : Info: rlm_sql (sql): Opening additional
connection (134), 1 of 31 pending slots used
Mon Apr 11 02:41:33 2016 : Auth: (62) Login OK: [xxxxxx] (from client
xxxxxxx port 0)


now I have lowered min,  I lowered it to several values including yet this
still logs.
I have tried more spares, more start/max servers, less servers, nothing I
do seems to make this thing happy and my boss does not like seeing logs
fill up with error type messages because he sees it as my failures, and
rightly so I guess.

My settings I think are related, and if I forgot some, please kindly ask
and ye shall receive.

radiusd.conf extract -
   start_servers = 5
   max_servers = 32
    min_spare_servers = 10
    max_spare_servers = 15
 max_requests_per_server = 0
 auto_limit_acct = no

from sql mod
     start = ${thread[pool].start_servers}

                #  Minimum number of connections to keep open
     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 = 90

We do not have a very busy radius, its for VPN and its rare everyone logs
in at once, we have currently two access servers, but soon will have one on
other states, so could be five in total by mid year.

Are my radiusd,c.onf settings overkill and this is why the logs fill up
with these errors?

Would anyone have more suitable settings advice?

Thank you.
