I have been tracking down an issue for months where SSH'ing to some
devices (which picks IPv6 by default) from my Mac while in the office
drops the connection, forcing me to reconnect. It's random; sometimes it
happens a lot, sometimes, rarely, other times not at all.
I've sort of suspected OS X to be the issue (10.10.5) here. The
workaround has been to SSH strictly on IPv4 which is always stable. So
it seems to be an issue when the session is carried over IPv6.
This only affects OS X. SSH'ing from FreeBSD, for example, on IPv6 is
stable. To be honest, I've been a little busy to look deeper into this,
but it definitely has something to do with what you describe, I imagine.
