> Project: MINA SSHD
> Issue Type: Bug
> Environment: Linux and Solaris
> Reporter: sivaprasad
> Priority: Blocker
>
> Hi Team,
> I hope all are doing great, I'm using Mina to execute remote commands
> execution and file uploads/downloads. everything is working fine, but while
> executing rsync commands( this command will take more than 1hr to complete)
> Mina is hanging forever and not returning anything.
> I have added HEARTBEAT in my code, but Mina is printing command output after
> command execution is completed but I need to print command output parallel
> with command execution.
> I have attached my code, can someone look into this and help me to resolve
> this issue’s.
>
> Thanks,
> Siva.
