[OpenSER-Users] tcp receiver with tcp socket?

Hi! I have configured openser 1.2 to only listen to udp: Starting Open SIP Router: Listening on udp: 1.2.3.4 [1.2.3.4]:5060 Aliases: *: mydomain.at:* $ openser-1.2-SVN/scripts/openserctl ps Process:: ID=0 PID=29582 Type=attendant Process:: ID=1 PID=29583 Type=receiver child=0 sock= 1.2.3.4:5060 Process:: ID=2 PID=29585 Type=receiver child=1 sock= 1.2.3.4:5060 Process:: ID=3 PID=29586 Type=receiver child=2 sock= 1.2.3.4:5060 Process:: ID=4 PID=29587 Type=receiver child=3 sock= 1.2.3.4:5060 Process:: ID=5 PID=29588 Type=receiver child=4 sock= 1.2.3.4:5060 Process:: ID=6 PID=29589 Type=receiver child=5 sock= 1.2.3.4:5060 Process:: ID=7 PID=29590 Type=receiver child=6 sock= 1.2.3.4:5060 Process:: ID=8 PID=29591 Type=receiver child=7 sock= 1.2.3.4:5060 Process:: ID=9 PID=29592 Type=timer Process:: ID=10 PID=29593 Type=tcp receiver Process:: ID=11 PID=29594 Type=tcp receiver Process:: ID=12 PID=29595 Type=tcp receiver Process:: ID=13 PID=29596 Type=tcp receiver Process:: ID=14 PID=29597 Type=tcp receiver Process:: ID=15 PID=29598 Type=tcp receiver Process:: ID=16 PID=29599 Type=tcp receiver Process:: ID=17 PID=29600 Type=tcp receiver Process:: ID=18 PID=29601 Type=tcp main process So, where does all the "tcp receiver" come from? If they are DB related maybe we should change the "Type". This proxy uses mysql for presence - this I guess all the TCP connections are for presence. But why do I have 19 mysql connections? $ netstat -anp|grep openser tcp 0 0 1.2.3.4:48896 1.2.3.68:3306 ESTABLISHED 29598/openser tcp 0 0 1.2.3.4:48897 1.2.3.68:3306 ESTABLISHED 29599/openser tcp 0 0 1.2.3.4:48898 1.2.3.68:3306 ESTABLISHED 29600/openser tcp 0 0 1.2.3.4:48899 1.2.3.68:3306 ESTABLISHED 29601/openser tcp 0 0 1.2.3.4:48900 1.2.3.68:3306 ESTABLISHED 29582/openser tcp 0 0 1.2.3.4:48889 1.2.3.68:3306 ESTABLISHED 29591/openser tcp 0 0 1.2.3.4:48888 1.2.3.68:3306 ESTABLISHED 29590/openser tcp 0 0 1.2.3.4:48891 1.2.3.68:3306 ESTABLISHED 29593/openser tcp 0 0 1.2.3.4:48890 1.2.3.68:3306 ESTABLISHED 29592/openser tcp 0 0 1.2.3.4:48893 1.2.3.68:3306 ESTABLISHED 29595/openser tcp 0 0 1.2.3.4:48892 1.2.3.68:3306 ESTABLISHED 29594/openser tcp 0 0 1.2.3.4:48895 1.2.3.68:3306 ESTABLISHED 29597/openser tcp 0 0 1.2.3.4:48894 1.2.3.68:3306 ESTABLISHED 29596/openser tcp 0 0 1.2.3.4:48883 1.2.3.68:3306 ESTABLISHED 29585/openser tcp 0 0 1.2.3.4:48882 1.2.3.68:3306 ESTABLISHED 29583/openser tcp 0 0 1.2.3.4:48885 1.2.3.68:3306 ESTABLISHED 29587/openser tcp 0 0 1.2.3.4:48884 1.2.3.68:3306 ESTABLISHED 29586/openser tcp 0 0 1.2.3.4:48887 1.2.3.68:3306 ESTABLISHED 29589/openser tcp 0 0 1.2.3.4:48886 1.2.3.68:3306 ESTABLISHED 29588/openser udp 0 0 1.2.3.4:5060 0.0.0.0:* 29582/openser Thus, why 19 DB connections for 8 UDP childrens? Why 8 tcp receivers in "openserctl ps"? thanks klaus
