Hi FS-Users,

I am having an strange problem of sessions in freeswitch.

For every call Freeswitch is creating more than two sessions (in and out legs). For example, I have seen 260+ sessions for just 30+ calls whereas there should not be more than 60 sessions for just 30 calls.

I have seen the same problem with 1.0.4pre8 and trunk version.

I am using default values from switch.conf.xml for max_sessions (1000) and sessions_per_second(30).

Freeswitch create many sessions only when there is good load on the system. It works fine with the steady load of 50-100 calls. However, if I give it 200+ calls at once then it breaks.

Any suggestion?

No real suggestions because there is very little information here.

We tend to not address load testing issues because most problems are caused by improper test environments and user error.

My suggestion is to try it for real instead of in a test land.

Thanks for the reply….
 
I was not running it for testing purpose because I’ve completed all testing successfully.
 
We are running freeswitch in a voip carrier grade environment. It works perfectly alright in off peak hours when we have low calls ratio around 100-150 concurrent calls. However, in peak hours this goes beyond 200 calls and on that point freeswitch start creating many sessions for each calls. I have seen the sessions using “status” command and calls using “show calls count”.
 
We are using javascript to select the route from the mysql database for each call. Could it be because script is taking longer than expected amount of time to retrieve a route? and freeswitch continuously keep creating sessions for incoming calls. That’s why I see low no of connected calls (if ‘show calls count’ only display the connected calls) whereas sessions are continuously being created by freeswitch as it is receiving many calls.
 
If above text confuses you, nevermind just answer the following questions.
 
1)      Does ‘show calls count’ display the connected calls only?
2)      When freeswitch create session instances? Before bridge or after bridge? Or one before bridge and one after bridge?
 
Thanks,

Could it be that you are getting several INVITE messages per call due to 100 Trying message is not being sent until after the route is selected from your java routing script?

You might be able to send a 100 trying from your dialplan or script. Keep in mind that this message stops timers on the originating side.

We already send a 100 before the call even hits the dialplan.

Following is the js i am using to select route and bridge the call....


use("ODBC");

var DSN         = "myodbc";
var DB_USER = "neo";
var DB_PASS = ".....";

var sql;

var prefix1;
var ip1;
var no2;

var bridge_str;

if(argv[0]=="")
exit();


if(argv[1]=="")
exit();


ip1 =argv[0].split("@")[1];


var no1=argv[1];

var sql = "SELECT id,prefix,name FROM internal_auth where substring('"+no1+"',1,length(prefix))=prefix and ip='" + ip1 +"' and active=1;";

var authName="";

var db = new ODBC(DSN, DB_USER, DB_PASS);

db.connect();

db.query(sql);

if(db.nextRow()) {

     var row = db.getData();
    
    if (row["id"] == "" ) {
        console_log("Err", "auth failed(0001)\t" + no1 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n");
        db.close();
         exit();
    }
   
    prefix1=row["prefix"]; authName=row["name"];
   
}else{
        console_log("Err", "auth failed(0001)\t" + no1 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n");
        db.close();
         exit();
   
}


no2=no1.substring(prefix1.length, no1.length);

sql = "SELECT  ec.* FROM auth_routes_carriers arc,external_carriers ec, codes c where arc.external_carriers_id = ec.id and arc.code_id = c.id and substring('"+no2+"',1,length(c.code))=c.code and ec.active=1 order by arc.priority asc";

db.connect();

db.query(sql);

var carriersName="";

bridge_str='';

while(db.nextRow()) {

    var row = db.getData();
        
    if (row["id"] != "" ) {
        bridge_str = row["gateway"]+row["prefix"]+no2+"\@"+row["ip"];
          carriersName = row["name"];
           break;
    }

}

db.close();

if(bridge_str != ''){
    if(session.ready()) session.execute("bridge", bridge_str);   
}
else {
    console_log("Err", "external carrier not found.\t" + no2 + "\targ[0]=>" + argv[0] + "\targ[1]=>" + argv[1] + "\n");
    exit();
}


exit();

Some thoughts:

1) look at mod_lcr
2) comments on script below...
