Hi All,
we are using jsch (mostly port forwarding) without any issue during
the last year. Today we deployed our app in a new environment which make
a lot more traffic (with peak of about 120/140 mbps). After it transfer
between 1 to 2 gb of data all data transfer freeze.
The forward is used by a standard rsync client that connect to a
"remote" rsyncd daemon.
Did someone have any hit on how to solve this issue ? Below I've
attached relevant data.
Thanks
Davide
