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.

HI again Ivan Do you know how can I modify the source code, in order to print in the error message the exact time when the child was created/forked? If I want to find errors in my sql backend server, I need to know the exact time when the requests are lost.. checking the code, It looks like this error message is printed only when the server detects threads that are stalled. Thx again.

No, you don't have a problem with radius server but with sql one. Perhaps you should look into the server that does have a problem (sql) and not the one that doesn't (radius). There is nothing radius server can tell you about why are sql queries running slow. Ivan Kalik Kalik Informatika ISP - List info/subscribe/unsubscribe?

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.

Re: Error: WARNING: Unresponsive child for request in module sqlcomponent accounting
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.
