Hello Pratima,
Slightly peripheral to the main thread, the remedy for your problem
reminds me of one that some of us had years ago.
FTX implemented https://www.ietf.org/rfc/rfc1323.txt section 3.2
wrongly, with 16 bit timestamps. The symptom was that, when the
16-bit timestamps rolled over, all of the incoming packets at the
other (linux) end would be filtered out, and the connection would
stall and then break.
Would you know if your counterparty was doing something like that?
Regards,
James.
