no fork mode means that there will be only one process listening for and
processing SIP messages. In addition to that there will be also the
timer process (taking care of timers) and fifo process (processing
commands sent to ser over the FIFO interface). The child init function
will be called for all of them. See:
root@localhost:/home/janakj# serctl ps
0 6266 stand-alone receiver @ 127.0.0.1:5060
1 6267 timer
2 6268 fifo server
If you want to execute the code in the listening process only, then you
can ignore calls of child_init that have the parameter set to PROC_TIMER
and PROC_FIFO (defined in sr_module.h).
Note that it is usually a good idea to have the same environment in the
timer process as in the receiver as some functionality might be called
from the timer.

Hello all,
I am trying to debug a new module that I have written.
So I have set fork=no and debug=4 and commented out the
child line.
The question I have is that the how may times the child_init()
function be called ?
The child_init() function in my module sets up a socket connection
to a server and I can see that the child_init() function is getting
called 3 times. I do not understand this. Am I missing something ?
The mod_init function is getting called only once, like it is supposed to.
I have attached the output from ser startup. The module that I have written
is called gl.
