Here you go, you can find the debug log from sample test server as
attachment.

The SSHD was started, then I tried to upload 43.5M file via WinSCP,
while RekeyLimit was set to "5M none" (just to speed up occurance of
rekey issue, without this it would happen at 1GB). As expected,
transfer broke at 5M with WinSCP reporting an issue "Server
unexpectedly closed network connection".

The example comes from the Gentoo OS, so it is compiled from the source
(this is a default installation approach on Gentoo) using the below
parameters:

net-misc/openssh-7.3_p1-r7::gentoo  USE="bindist hpn pam (pie)
(selinux) ssl -X -X509 -debug -kerberos -ldap -ldns -libedit
(-libressl) -livecd -sctp -skey -ssh1 -static {-test}" 0 KiB

Regards,
Artur
