Hello Ali,

(please keep the sr-users list in CC, that other people can also participate)

Remove the “-D” from your Kamailio command line – then the warning will disappear. This is also necessary because you want to have Kamailio listen on several addresses. If you want to test it more in a production like setting, you should also remove the “-E” from the command line. You will find the logging in your system log then.

Cheers,

Henning

Dear Mr.Henning,

I am working on high availability on two Kamailio servers connected to the database using keepalived and when I am testing Kamailio

I got this issue and I have no idea about fixing it

i am trying to see by this command

kamailio -E -D -f /etc/kamailio/kamailio.cfg

Hello Ali,

the first warning is related about the starting mode of Kamailio. You should not start it with “no forking mode” if you want to get rid of it. Have a look to your command line parameters: “-D” is the one to change.

Cheers,

Henning
