> Hi Lyor,
> We have an Apache SSHD 2.2.0 client and server SSH pair used for local port
> forwarding of different protocols.
> In our lab environment we found that sometimes when the SSH client for any
> reason is disconnecting from the SSH server, a DEADLOCK happens on the
> sshClient regarding the threads in the thread pool.
> We are using builtin nio2 implementation for our SshClient.
> The deadlock is regarding the ClientChannelPendingMessagesQueue class added
> to fix routing problems for local port forwarding in the past.
> Attached you can find the thread dump taken after the deadlock happend.
>
> Can you please troubleshoot this problem ?
