<p><br>Appreciate if any one can tell me what cause the problem.<br>I suspect something like connection leakage cause the correct port cannot be used, but what can cause that? Besides, why a strange IP address 172.50.10.102:6666(the IP of two servers are 172.50.10.1 and 172.50.10.2 respectviely) appears when error occurs?<br>
Any help is appreciated.<br>Thank you very much. </p>
<p>Best Regards<br>Jia Jian Ping</p>
