[OpenSIPS-Users] Process List Question

[Schumann Sebastian]

Hi

You can check the processes in detail using the FIFO command
$ opensipsctl fifo ps
(FIFO must be enabled).

The processes are almost as Inaki described. 

In detail, it should be like this:
1. UDP WORKER (SIP) x children x interfaces
children=10
listen=10.0.0.1:5060
listen=10.0.0.2:5060
-> 20 processes finally, so children for each interface

2. TCP WORKER (SIP) x children
tcp_children=5
listen....... does not matter, fixed number of processes handles it. If no tcp_children is set and TCP enabled, the children number is used.
--> 5 processes

3. TCP MANAGER x1

4. TIMER PROCESSES (multiple possible)

5. ATTENDANT x1

Sometimes, also modules can require additional processes.

It depends on the number of interfaces and transport protocol (TCP/UDP) in 
which opensips is listening. If you set "children=4" and listen in eth0 for 
TCP and UDP then you will have 4*2 + main process = 9 (well, it's something 
like this but not exactly).
