Connection dropped with Sunquest inbound thread

[Hongle Sun]

we have a problem of receving inbound messages from Sunquest, bascially this is typical inbound thread with TCP/IP using, from process log i can see the ack outbound msg created. But Sunquest says that did not receive and end up with sending the identical message over and over, and Sunqest do a system level telnet and saw the connection was droppe at cloverleaf box end, what should i look into? Thanks in advance

Depending on the protocol used, if set to pdl-tcpip or tcpip, it may be that “Close after write” is set in the threads protocol properties.

If this is the case, then they are not handling things properly on their end. The suggestion for this is to see if disabling this helps. If the connection has to be closed by cloverleaf, then they will need to fix their socket code.

If “Use DRIVERCTRL control” is set and you are setting CLOSE to 1 in the DRIVERCTL, then this will be the issue, as the control message is actioned before the message is sent. You will have to change the setup to use “Close after write” and not set the DRIVERCTL with CLOSE
