FreeRadius + MySQL | radacct: Errors and Warnings

[Daniel Menezes]

Hi all,

First, sorry my bad English.

I have a FreeRadius + MySQL setup with MikroTik as NAS.
And a few days ago I have some warnings and errors in the log:

Tue Oct 25 04:02:41 2011 : Info: Released IP xxx.xxx.xxx.xxx (did
via-pppoe-01 cli xx:xx:xx:xx:xx:xx user dmnzs-test)
Tue Oct 25 05:30:36 2011 : Error: Received conflicting packet from client
my-pppoe-01 port 39595 - ID: 75 due to unfinished request 625066.  Giving up
on old request.
Tue Oct 25 15:43:20 2011 : Error: WARNING: Unresponsive child for request
784, in module radutmp component accounting


I read something about slow backend, tables indexes and other things.
I've used the backend script 'mysqltuner.pl' to adjust the performance.
It's better now, but the warnings and erros persists.

Can anyone help me on this?
Thanks in advance.


Sds,
