1, peripheral platform has a deal needs to go through the socket in the day, through the message form to I send information platform, before this part of the deal is normal,
According to business needs, now my platform of 18 server migration to 145 machine, lead to peripheral platform message cannot be sent to me, cause the failure of transactions,
Through caught tools after I gave a monitoring platform:
Tcpdump TCP port 10003 - grab 10003 packages
Netstat anc | grep 10003-10003 detection of port state change
Look at the grab bag, only one Flags during [P] state of package, and most of them are Flags [.], Flags [.],
Preliminarily concluded that is three times handshake protocol TCP/IP is not established, cause I platform doesn't receive peripheral platform message, and I have no record of platform log information to the wrong information about the deal,
And 10003 port when trading, keep state SYN_RECV,
Please everyone a great god, according to a grab bag of information I have provided help me determine what causes this message not send a success? And should be from the aspects of illness? And have a good command can help to troubleshoot, thank you

Tcpdump TCP port 10003
