Hi Neal,
Unfortunately with the patch we still see the same stack trace. Attached
is the TcpExtTCPSACKReneging with the patch, captured with 60 seconds
interval. Its value is incremented at an similar speed as before, about
30/minute.
If you want to collect any other data, please feel free to let me know.
Thanks,
Grant

Thank you Neal. Most likely I will test the patch on Monday and report
back the result.
As for the TcpExtTCPSACKReneging counter, attached is the captured
counter value on a 1-second interval for 10 minutes.
OK, great. Those TcpExtTCPSACKReneging values look consistent with the
theory underlying the patch, so that's a good sign.
Thanks!
