[erlang-questions] Debian ARM: Three beam processes

Hello all,

I've realised a curious behaviour in erlang debian package. When I
call erl, three processes are created with the same erlang name, as
you can see below. I know this is not usual (at least in Mac OS X and
FreeBSD in which I usually develop), any idea? Help would be
appreciated...

I'm using Debian: Linux bs0 2.6.18-3-ixp4xx #1 Tue Dec 5 16:52:07 UTC
2006 armv5tel GNU/Linux
ARM Architecture:  XScale-IXP42x Family rev 1 (v5l)
Erlang package version is 11.b.2-4.

The unusual behaviour:

$ ps ax |grep beam
2569 pts/0    S+     0:00 grep beam

$ erl -sname dontknowwhy -detached

$ ps ax |grep beam
2581 pts/0    S      0:01 /usr/lib/erlang/erts-5.5.2/bin/beam -- -root
/usr/lib/erlang -progname erl -- -home /home/mrrubinos -sname dontknowwhy
-noshell -noinput
2582 pts/0    S      0:00 /usr/lib/erlang/erts-5.5.2/bin/beam -- -root
/usr/lib/erlang -progname erl -- -home /home/mrrubinos -sname
dontknowwhy -noshell -noinput
2583 pts/0    S      0:00 /usr/lib/erlang/erts-5.5.2/bin/beam -- -root
/usr/lib/erlang -progname erl -- -home /home/mrrubinos -sname
dontknowwhy -noshell -noinput
2589 pts/0    S+     0:00 grep beam

One of the strangest things is that at this point there are three
erlang nodes with the same name and no erl_crash.dump.

Thanks in advance,

          Miguel
