Hi,
I have an issue where a socket is opened to a server and remains open for long periods of time. Data is sent and recieved over this socket. After an indeterminate amount of time the connection becomes very slow.
I am only just starting to trace into this and have just implemented the percipio tracalyzer to help in debugging.

under normal operation I can see
RX 1120 bytes
tx 54 bytes
tx 91 bytes
repeat

under the fail case i see
RX 1120 bytes
tx 54 bytes
tx 91 bytes
rx 60 bytes
tx 91 bytes
repeat

does anyone have any clue as to where to go from here or perhaps a reason for the issue.
