The local and remote IP addresses are the same? That seems odd to me.
Maybe this is IPC – inter process communication? I would expect it to use 127.0.01 (localhost) though rather than the IP of the system.
It sounds like the application sent a FIN to close a TCP connection but did not receive the FIN/ACK and therefore was unable to acknowledge with another ACK and then a FIN/ACK for a final close. See this diagram for TCP connection states. The FIN timeout is a normal TCP operation. Unless you are seeing any issues with the application listening on port 5544 then I would say this is not an issue.
In the IT trenches? So am I – read my IT-Trenches blog.
Turns out its a PTF issue. We are behind a few PTF’s. It all has to do with iSeries navigator. I started a monitor job piece to send us emails when a certain subsystem has a problem. It was not responding correctly b/c of a PTF issue. So I’m downloading PTF’s now and we will see what happens… Stay tuned….!
