Hi!
<br>
<br>
I have configured openser 1.2 to only listen to udp:
<br>
<br>
Starting Open SIP Router:
<br>
Listening on
<br>
udp: 1.2.3.4 [1.2.3.4]:5060
<br>
Aliases:
<br>
*: mydomain.at:*
<br>
<br>
<br>
$ openser-1.2-SVN/scripts/openserctl ps
<br>
Process:: ID=0 PID=29582 Type=attendant
<br>
Process:: ID=1 PID=29583 Type=receiver child=0 sock= 1.2.3.4:5060
<br>
Process:: ID=2 PID=29585 Type=receiver child=1 sock= 1.2.3.4:5060
<br>
Process:: ID=3 PID=29586 Type=receiver child=2 sock= 1.2.3.4:5060
<br>
Process:: ID=4 PID=29587 Type=receiver child=3 sock= 1.2.3.4:5060
<br>
Process:: ID=5 PID=29588 Type=receiver child=4 sock= 1.2.3.4:5060
<br>
Process:: ID=6 PID=29589 Type=receiver child=5 sock= 1.2.3.4:5060
<br>
Process:: ID=7 PID=29590 Type=receiver child=6 sock= 1.2.3.4:5060
<br>
Process:: ID=8 PID=29591 Type=receiver child=7 sock= 1.2.3.4:5060
<br>
Process:: ID=9 PID=29592 Type=timer
<br>
Process:: ID=10 PID=29593 Type=tcp receiver
<br>
Process:: ID=11 PID=29594 Type=tcp receiver
<br>
Process:: ID=12 PID=29595 Type=tcp receiver
<br>
Process:: ID=13 PID=29596 Type=tcp receiver
<br>
Process:: ID=14 PID=29597 Type=tcp receiver
<br>
Process:: ID=15 PID=29598 Type=tcp receiver
<br>
Process:: ID=16 PID=29599 Type=tcp receiver
<br>
Process:: ID=17 PID=29600 Type=tcp receiver
<br>
Process:: ID=18 PID=29601 Type=tcp main process
<br>
<br>
So, where does all the "tcp receiver" come from? If they are DB related
maybe we should change the "Type".

Both udp and tcp receiver process is forked to handle SIP messge. You
can disable TCP using flag "tcp_disable=yes". Because openser default
support tcp link. So you can see tcp receiver though you config
"listen=udp: 1.2.3.4:5060". For detailed information<br>

Thus, why 19 DB connections for 8 UDP childrens?

I guest one mysql connection for each process. Here you have 8+1 udp
process, 8+1 tcp process, 1 timer process, sum them up,you get 19
connection. Am I right?<br>
