masc edited comment on SSHD-743 at 4/24/17 4:43 PM: ---------------------------------------------------- * The issue occurs since `1.3.0` but `1.4.0` was tested as well and didn't make a difference. * Yes, it breaks the client connection plus the exception is leaking from the thread (that we don't own) terminating the entire host process. * Yes we are primarily tunnelling rsync. We set the idle timeout for ssh tunnels to 3 minutes on the host side and leave write timeouts at their defaults. Those settings work fine with `1.2.0`. was (Author: masc3d): * The issue occurs since `1.3.0` but `1.4.0` was tested as well and didn't make a difference. * Yes, it breaks the client connection plus the exception is leaking from the thread (that we don't own) terminating the entire process. * Yes we are primarily tunnelling rsync.
