I have a 275 MB queue on both machines.. I have 250 MB of RAM on both machines; one is a single PII 450, the other dual PII 450 MHZ processors machine from SW Technologies. I just noticed that my ldm.pq is 281 MB, so it is exceeding the limit I have specified slightly. But I haven't had any problems with it that I am aware of.
