[Serusers] Ser start but no PID

Hi, I compile SER 0.9.6 from source on a computer running Fedora Core 4. I suppose make all, make install all go well as I can't see any warning or error. When I start ser, it seems normal but I can't find the pid with ps. [root@localhost ~]# serctl start Starting SER : started pid(18726) [root@localhost ~]# ser Listening on udp: 127.0.0.1 [127.0.0.1]:5060 udp: 192.168.1.4 [192.168.1.4]:5060 udp: 192.168.1.17 [192.168.1.17]:5060 tcp: 127.0.0.1 [127.0.0.1]:5060 tcp: 192.168.1.4 [192.168.1.4]:5060 tcp: 192.168.1.17 [192.168.1.17]:5060 Aliases: tcp: localhost:5060 tcp: localhost.localdomain:5060 udp: localhost:5060 udp: localhost.localdomain:5060 [root@localhost ~]# serctl stop Stopping SER : /usr/local/sbin/serctl: line 813: kill: (18726) - No such processstopped [root@localhost ~]# How can I fix this so ser run normally? Thank you. -- Best regards, Linh Pham
