looks like one of the commands failed (probably the first one)

the command is working.

Your 'mqhost' might call stty(1) for some reason. strace -f is your friend

Sorry I'm newbie how can i use it?

I think I got this error since 'mqhost' is tcsh script.

is there any way to run is?

see man strace, but actually it is quite simple:
strace -f -o <your_log_file> <original_command>
