Six TCP Retransmissions with RTO 0.0009s

Hi,

I am having a problem with a TCP connection between services inside the same server. It is an application server and a SQL Server. When I collected the network traffic from the loopback adapter, I can see that the package, six retransmissions, and the connection reset are transmitted in less than a second. I thought we would have at least some seconds between the first package and the reset due to a connection issue.

Before the network issue, we have some seconds without any package collected, and I guess that the server is freezing for some reason, and it is creating this network failure.

Does someone here know if it is possible or has an explanation for that?

Thank you

Just pondering wether or not the measurement is accurate here.You might be looking for the wrong problem here so if anyone can share their thoughts about the accuracy of loopback traffic in wireshark.
