I have a question on this, since 180 arrived before the 200, shouldn’t it go out before? I.e.: FIFO? Or is this not happening because there are multiple processes and one may take the 180 and the other the 200 and they are processes independently?
I guess setting the childs to only 1 should prove this theory.
In theory, it should all be FIFO, of course. In practice, there are stochastic aspects to OS process scheduling and I/O scheduling which make the ingress and egress of messages arriving at Kamailio simultaneously or substantially simultaneously somewhat indeterminate.
And, of course, it depends on how complicated the processing of the messages respectively is, either in computational terms, or external I/O wait, or both.
To Steve Davies' point, that's just the nature of the multiprocess architecture, together with the lack of a distributor thread.
