Stream.record suddenly stops

Hey guys.

I'm having really strange situation here and tought maybe u can give some tip, where to search.

im recording stream on server side with simple function:

var l_s = Stream.get(someNameHere);

l_s.onStatus = function(info){

        trace("RECORDING STREAM ON STATUS: ")

for (var i in info ) trace ("    "+i+": "+info);

trace(">>>>>");

};

if (l_s)

{

var l_success = l_s.record("record");

l_s.play(p_info.path, -1, -1);

}

now its the strange part:

for some reasone stream is being recorded for some random time like 1MB, other 5MB other 12, etc and then suddenly without any onStatus information (which is traced) it stops recording. Live stream is being published normally, but recording suddenly stops without triggering onStatus event.

would appreciate any help
