-----------------------------------
Summary: Ssh server freezing when under heavy load
Key: SSHD-393
URL: https://issues.apache.org/jira/browse/SSHD-393
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 0.13.0, 0.12.0
Reporter: Maros Marsalek
When using the Ssh server and writing big amounts of data towards the client,
server can freeze waiting for window adjust msg.
It always happens after server gets into state of delaying write while waiting
for window adjust. After the window adjust is received, write is not resumed.
There is no mechanism to resume the write for server side, but on the client
side there is.
We have a junit test case that reproduces this issue. We were able to fix it
with this patch:
