In code I very often call gproc like this:

handle_cast({msg, To, Message}, State) ->
    spawn(fun() -> 
            % Trying to lookup Pid from gproc
            case gproc:lookup_local_name(To) of
                undefined ->
                    % player is not loaded, loading the player
                    player:start(To, Message);
                Pid ->
                    % player is here, passing the message to him
                    gen_server:cast(Pid, Message)
    {noreply, State};
handle_cast(_Msg, State) ->
    {noreply, State}.

In module player I work with grpoc like this:

init([Name]) ->
    % Registering in gproc
    ?LOG("Creating new process", Name),
    {ok, #state{name = Name, ready = 0}}.

From time to time I see something like this in my logs:

=CRASH REPORT==== 8-Jan-2012::01:50:52 ===

What could be the reason for this? Is this because of gproc of my code?
