Unresponsive child for request
I am getting this error in my logs and I understand it is do to likley an issue with sql but was wondering what the criteria for this error to be generrated is.

Re: Error: WARNING: Unresponsive child for request in module sqlcomponent accounting
Thx Alan
I coded a very simple script to check the mysl server latency:
#!/bin/sh
ExecQuery ()
{
echo select count(*) from radacct; | mysql -h mysqlserver -u
radiususer --password=radiuspassword radaccoutingdb
}
while [ -n 1 ]
do
echo -n starting query.
date
time ExecQuery
echo -n query finished..
date
echo
echo
sleep 300
done
Executing this script during last 24h (with nohup), from the radius machine, I
got always latencies below 1 second
How can the script get always latencies under 1sec, and the radius threads on
teh other hand get latencies over max-request-time?
I'm a little bit lost :(
thx again

That message is printed max_request_time seconds after the packet is
received. The stall happens at some point during that time period.

Executing this script during last 24h (with nohup), from the radius machine, I got always latencies below 1 second Below 1 second or below 1/100th of a second? Near 1 second for such a simple query is *very* slow. Have in mind that insert into radacct is going to take some 100 times longer then a select.

Re: Error: WARNING: Unresponsive child for request in module sqlcomponent accounting
First, optimize your database, add indexes and use storage engines which will give you the best performance... Increase interim-update interval After that, try to add more handlers and see what will happen. If you're using mysql, check tuning-primer.sh and mysqltuner.pl scripts.

Error: WARNING: Unresponsive child for request in module sql component accounting
Hello all!!
I facing this problem with my Freeradius 2.1.3, and I don't know how to solve
it :(
My NAS is sending only accounting registers to my freeradius server. My
freeradius server, is configured to store these registers into a MySQL server.
I have configured max_request_time = 120, in the case of MySQL slow
performance, but the problem perssits.
My questions are:
- how can I solve this issue?
- When a child is unresponsive, the register is lost, or another child stores
it into the database?
Thx in advance.
Regards

Thx Ivan, and do you know if the accouting registers is lost? or another child retries the insert into the database? thx Regards On Miércoles 25 Febrero 2009 14:09:44 t...@kalik.net wrote: I facing this problem with my Freeradius 2.1.3, and I don't know how to solve it :( My NAS is sending only accounting registers to my freeradius server.

Re: Error: WARNING: Unresponsive child for request in modulesqlcomponent accounting
and do you know if the accouting registers is lost? or another child retries the insert into the database? They usually are - there are no handles to write to the database as the whole server gets blocked. I haven't seen tha case where single handle would dia and the rest of them would continue working. This is usually terminal state of radius-sql server connection problem. Ivan Kalik Kalik Informatika ISP - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
