dbg question

[Robert Balogh]

Hi Ulf,

I checked this Pid, and unfrotunatelli is not alive.

Erlang (BEAM) emulator version 5.3 [threads:0]

Eshell V5.3  (abort with ^G)
(axd301@REDACTED)1> Pid = dbg:trace_client(ip, {"cp1-1", 4711}).
<0.37.0>
(axd301@REDACTED)2> is_pid(Pid).
true
(axd301@REDACTED)3> is_process_alive(Pid).
false

How possible to start this dbg client? Do you have any idea? I read the dbg 
module quide about 10 times, and at this time I think I don't understand how 
works it :-(

tahnks,
Robi
