Can you confirm that adding shutdown(MyProcPort->sock, SD_BOTH) fixes
the issue for many test runs?
I don't see the stable test passing here.
Without shutdown() the test failed on iterations 1, 5, 4, but with
shutdown() it failed too, on iterations 3, 1, 4.
Without close() and shutdown() the test passes 20 iterations.
(I'm still researching how openssl affects the shutdown sequence.)
Best regards,
Alexander
