I get that too, if I supply the same arguments. The problem is that
the "gdbclient" shell function isn't doing what you think it's doing.
The third argument isn't a pid, it's a process name, which is fed to
the "pid" shell function to determine the process ID.

If you instead do:

% gdbclient mediaserver :5039 mediaserver

you'll have much better results. (It took me a minute to figure that
out -- the big clue for me was that when you disconnect gdb the remote
end is killed, but in this case the mediaserver process wasn't dying.)
