I'm unable to reproduce SSHD-1031 locally - it occurs on production under heavy
load.

[~xvost] does it also solve SSHD-1031 ? I suspect these issues are related.

I've investigated the issue deeper and have an idea how this could happen, and
this looks like a race in sshd code.
In ChannelAsyncOutputStream class in doWriteIfPossible method you have the code:
{code:java}
int total = buffer.available();
if (total > 0) {
Channel channel = getChannel();
Window remoteWindow = channel.getRemoteWindow();
long length;
if (total > remoteWindow.getSize()) {
// if we have a big message and there is enough space, send the next
chunk
if (remoteWindow.getSize() >= remoteWindow.getPacketSize()) {
// send the first chunk as we have enough space in the window
length = remoteWindow.getPacketSize();
{code}
Looks like remoteWindow.getSize() is changes asynchronously, thus length get
the packet size (in my case 32k), and then it fails to copy buffer since buffer
length is 16k only.
I've proved this hypothesis by setting breakpoint on the "length = ..." line,
and it was hit, and in that exact moment condition "total >
remoteWindow.getSize()" is FALSE

Ok, I can reproduce the problem locally quite easy. The problem usually occurs
when a couple of GBs already sent into channel.
The only strange thing I see in logs that an exception is prepended by a number
of SSH_MSG_CHANNEL_WINDOW_ADJUST messages without sending actual data frames

Nope, the buffer is not reused. The write loop looks like this (in Kotlin): -
it just reads data portion from pipe and sends it into SSH channel
{code:java}
do {
val buffer = ByteArray(8192)
val read = pipe.read(buffer)
if (read > 0) {
try {
ioOut.writePacket(ByteArrayBuffer(buffer, 0, read,
true)).awaitWrite()
} catch (ex: Throwable) {
throw IOException("Error writing $read bytes. Channel: ${ioOut}",
ex)
}
}
} while (read > 0)
{code}
I will do exhaustive testing tomorrow with debug logging enabled, and hopefully
will provide logs with more details

Thanks, this provides more information - I'll look into it.

No, this is not related to SFTP code. The server application receives incoming
SSH requests and handles the command execution by itself (Actually, the
commands are domain specific for application).
The provided stacktrace are the only frames involving mina.sshd - all frames
above are from my application. I do the following (Kotlin language):
{code:java}
val buffer = ByteArray(8192)
. fill buffer with actual data to send.
IoOutputStream.writePacket(ByteArrayBuffer(buffer, 0, min(length, 8192), true))
{code}

This may be related to some SFTP changes we added involving the use of async
streams. Can you confirm that this is the use-case here ? Are you using SFTP
when this occurs - if so what is the code trying to do - read/write/sth. else ?
In any case, can you provide the full exception stack trace ?
