When I run some command in a remote ssh that does a lot of output, like -j 5 on fast SMP machine, I regularily get:

Disconnecting: Bad packet length 542322766.

from the local ssh client. Remote machine is running NetBSD-current as well.
The exact bogus packet length value is more or less random.


No idea, happens "often" for me. The peer is behind a VPN, MTU and high
latency issues might apply. The VPN link gained some bandwith lately, I think
I haven't seen it before that (but it might have started with the latest
openssh/openssl import as well)

no idea, sorry.
