This is because the rekey-logic doesn't handle changed hostkeys too
well in the fly (it is a known bug, which will be fixed for the next
release).
Does the host key change during the connection? When you connect, does
it complain about a changed hostkey?
: This is clearly a bug in 2.3.0. (a severe one IMHO!)
Yes and no. The rekeying feature improves security, because the
security and integrity keys are changed once every hour (by default,
you can change it, or diable it altogether).
It is a bug, however, to bomb like you describe if the host key is
changed during your terminal session. Will be fixed.
