Fulvio Cavarretta updated SSHD-776:
-----------------------------------
Attachment: dmzagent-WriteAbortException.trc
Hi [~lgoldstein], we integrated you modifications in the 1.6.0 codebase and
recompilaed in our environment.
We also added a trace when the new _WriteAbortedException_ is set
see. line 2165 in [^dmzagent-WriteAbortException.trc]
I could not understand why in _Nio2Session.doCloseImmediately_ _writes.poll()_
is not empty, but setting the exception lead the session to be closed.
Do you think that changing the code to:
{code}
@Override
protected void doCloseImmediately() {
for (;;) {
// Cancel pending requests informing them of the cancellation
Nio2DefaultIoWriteFuture future = writes.poll();
if (future != null) {
log.warn("Write request aborted due to immediate session
close");
future.setWritten();
} else {
break;
}
}
...
{code}
can be possible solution ?

> Apache SSHD used in local port forwarding mode.
> A client is connecting to a remote FTP server through Apache SSHD via a
> custom software.
> When a new logical channel inside a single SSHD session get an IO error (e.g.
> the remote destination close the connection suddenly, the whole session is
> shut down causing all other logical channel to be closed (see line 8861of
> attached trace file).
> It seems like the _exceptionCaught_ mathod should not be called in this case
