Hello Alex,<br>
<br>
to understand what I meant with syslog and asyncronous, see next

The syslog I have is the standar centos installation. I don't
understand what you mean. The benchmark module I haven't use yet.(I
finding it a bit difficult to use :-( )<br>
BUT<br>
I found this:<br>
In my kamailio.cfg I had some extra logging fields (acc extra
accounting) in the mysql and also the cdr in mysql. That is giving
heavy load in mysql and I see many call failing. I disabled that and
now I have a CPS 40 with concurent calls 12.000. The failed calls are
11 only. This seems good. <br>
But even I'm NOT logging CDRs in mysql I still see mysql in 70% CPU
load and I don't understand why. I beleive that Kamailio when is
starting up is getting into memory all mysql data, in my case from
PDT,Dialplan and Dispatcher tables.<br>
<br>
So the question now is why mysql is working so hard ?<br>
</blockquote>
<br>
Activate query logging for mysql and see what it does. Do you have any
authentication in the config?<br>

I'm also sending you my kamailio.cfg because maybe you can see
something I haven't mention..<br>

<br>
You haven't send it -- do it to private address, so you protect
confidential data like usernames, passwords, IPs, etc.<br>
<br>

We don't have packet loss and the log level is 1.<br>
Concerning the the asyncronous loging: This should be set before

This functionality can be enabled with setting the define SYSLOG_ASYNC
in the Makefile.defs file. The default is the normal log functionality
from the system library, nothing changed if the define is not set.<br>
</blockquote>
</div>
no, it is not about this. By asynchronous syslog I meant the syslog
config in the system, nothing related to source code of kamailio.<br>
<br>
If the log level is 1 then you should not see many syslog messages.<br>
<br>
Maybe is better to use the benchmark module to identify where is the
delay coming from (if it is from kamailio config).<br>

users,<br>
<br>
I'm using kamailio in the following scenario:<br>
<br>
1. A call comes in and is checked against PDT module. From this module
depend from the prefix I'm getting back the domain which is used as the
dialplan group.<br>
2. After that the call is checked against Dialplan module using the
previous value from PDT as Dialplan dpid. From the Dialplan module i
get back the the attributes values.<br>
3. these attributes values are user in the dispathcher module where I
continue with failover scenarios.<br>
<br>
Also the script is working with a radius for accounting purposes.<br>
<br>
This scenario works perfecttly and it is still in a testing mode.<br>
<br>
An the problem:<br>
<br>
I'm running SIPP against this scenario and until the CPS is 5
everything looks good. The scenario for SIPP is the simplest. uac and
uas default. Uac is sending a call and uas is answering.<br>
When the CPS goes above 9 then I have call failures. All the statistics
are going down.<br>
I'm cheking for CPU load or other system problems but I don't see
anything strange. Does anyone understand why this is happening?<br>
</blockquote>
</div>
do you have high debug level? Is your syslog configured asyncronous?<br>
<br>
Are network packets dropped from the network interface?<br>
<br>
Cheers,<br>
