I am currently facing an issue in my application where the TCP messages seem to be blocked until an acknowledgment received. Specifically, the subsequent messages wait for the acknowledgment of the first message before continuing transmission.
I ruled out the window size as the potential cause, as the window size is set to 29200, while the packet length remains at a comfortable 290. To provide more context and details, I have attached a screenshot of the pcap for your reference.
I would greatly appreciate any insights, suggestions, or guidance that the community can offer to help me identify and resolve the root cause of this delay.
Thank you in advance for your time and assistance.
