Hi,
I am using Kamailio v.5.8.4 on Ubuntu 24.04, kernel 6.8.0-51-generic
In the configuration script I explicitly set $fs="udp:adrr:port". In normal situations, it works properly and I see that the UDP SIP requests are sent from the requested IP and port.
Due to some reasons, free space on the server root filesystem was exhausted.
I cleaned up the file system and everything looked good except the fact that Kamailio started to send messages from ephemeral IP ports instead of the port defined in $fs.
Restart of Kamailio didn't solve the problem.
But the server reboot fixed the issue.
I don't understand how the lack of free disk space can cause such a problem and I'm afraid that there is another reason that I am missing.
Has anybody seen such a problem?
