No, the GC will only take place "after 50MB of allocation". IOW this setting just makes the GC less frequent (which in turn means that there will be more fragmentation and that each GC will take longer). This setting is probably more harmful than useful, but it's unlikely to have anything to do with your problem. Stefan
