[OpenSIPS-Users] Error in TURN Servers

Check again, there are not thousands processes but the processes you are killing are just "restarted". This is not a problem at all...

There is a parameter in Opensips which adjusts the number of child processes, change the parameter, restart opensips and count the number of processes again.


openSIPS | Documentation / Core Parameters - 2.2<https://www.opensips.org/Documentation/Script-CoreParameters-2-2#toc34>
3. Core parameters. Global parameters that can be set in configuration file. Accepted values are, depending on the actual parameters strings, numbers and yes/ no.

But anyways it's very obvious that the issue is something specific to TURN and not Opensips:


Coturn/turnserver : error 437: Mismatched allocation ...<https://stackoverflow.com/questions/36627529/coturn-turnserver-error-437-mismatched-allocation-wrong-transaction-id-webr>
I have this structure : Web server : Apache. it's in a LAN. It is on a pc (windows 7) which has public static ip. PC is in a network. Signal server: In a VM ...

It probably has something to do with the combination of client/server/configuration, but not the SIP Server.

The screenshot doesn't show all the processes but I know it is hundreds because it's necessary to run 'killall' or similar command several times to get rid of all the processes and I can see the PIDs change each time.

I think it absolutely can be OpenSIPS server causing the TURN error because OpenSIPS is in charge of creating the sessions in the first place, and if there are hundreds of OpenSIPS processes running then there will be hundreds of sessions created for each call.

I don't see hundreds or even thousands on the screenshot?

Also the Opensips server should not have any connection/relation to your TURN Server, so i don't think Opensips could be the issue.

A quick google search for "TURN 437 Allocation Mismatch" suggests that it's a TURN CLIENT <--> TURN Server problem. It could be related to the TURN client implementation.

Anyone? I am using OpenSIPS version 2.2.

I found the cause of this. My OpenSIPS server has gone ballistic and is running hundreds of processes/instances concurrently; please see this screenshot: https://www.dropbox.com/s/7o7fsuab1jggrsh/Screenshot%202017-08-10%2007.28.15.png?dl=0

Even after I kill all the processes, hundreds of processes start again whenever I start OpenSIPS in any way.

Below is my opensips.service file but the same occurs if starting OpenSIPS using 'opensipsctl start':

Description=OpenSIPS is a very fast and flexible SIP (RFC3261) server
After=network.target mariadb.service multi-user.target

ExecStart=/usr/local/sbin/opensips -P /var/run/opensips.pid -f /usr/local/etc/opensips/opensips.cfg $OPTIONS
ExecStartPre=/usr/local/sbin/opensips -c -f /usr/local/etc/opensips/opensips.cfg


Please advise how to fix this urgently.
