-bg option problem

[zhendehaofan]

I have a problem when i use -bg option:

1. Environmental: centos7,seagull 1.8.3,sctp,wireshark;
2. Server command line:
   seagull -conf link.xml -dico ../dict/base_cx.xml -scen scene.xml -log sctp_svr_rcv.log -llevel ET -bg
   Background mode - PID [26823]
   ps aux | grep seagull root 26823 0.2 0.2 180196 2556 pts/1 Sl 21:02 0:00 seagull -conf link.xml -dico ../dict/base_cx.xml -scen scene.xml -log sctp_svr_rcv.log -llevel ET -bg

3.Client command line:
seagull -conf link.xml -dico ../dict/base_cx.xml -scen scene.xml -log sctp_clt_snd.log -llevel ET

The server and client are run in 2 terminals in one machine. But the test failed. i can find the client send 3 sctp init messages in the wireshark capture, the server doesn't send ack.The following is the log .

If the command line has no -bg option,the test is successful.

please help me.how can i fix this problem.

I want to remote run seagull and remote control by restful api:

1. remote run:
   windows(python) -------------ssh--------->centos(seagull server)
2. remote control:
   windows(python) ------------restful-------->centos(seagull server)

in the first step, the -bg option must be used.but now it cannot create sctp link successful.
Thank you very much.
