I was troubleshooting slow file upload issue. Here I can observe multiple dupacks, which could be pointing to packet loss. Additionally here on trace (tcptrace graph), it can be observed some instance when the data segment surpassed receive windows on tcp trace graph.

In simple words - blue line overlaps the green line. Now I need to know why it happens.

Wireshark can help show you what is happening, but it usually isn't very good at answering why it's happening. Perhaps if you could post a capture file somewhere, then someone might be able to help you analyze it.
