For the record this is due to some name mangling on the part of FreeBSD:
https://github.com/freebsd/freebsd/blob/master/crypto/openssh/ssh_namespace.h#L496

so misleadingly the error actually comes from opacket.c:packet_write_poll()
and not packet.c:ssh_packet_write_poll().

I would guess that something on the server (maybe a firewall) is causing
either accept() or read() on high numbered ports to fail with EPERM.  I'd
suggest you strace/truss/ktrace the sshd immediately before triggering the
failure and look for what's EPERMing.

usually comes from bad judgement.
