Thanks, for the advice. The :pty flag fix the problem. I do know that
the process is not running on the server and it is not buffer related
before the pty flag. When this task running, it will consume very high
cpu load on the server, also the task was never finished.
For some reason, pty solved this problem. When I tried to run on command
line something like this ( ssh hostname "task name"). I got wierd error:
Pseudo-terminal will not be allocated because stdin is not a terminal.
Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.
Thanks!
