Agreed, advisory backoff seems to do a pretty good job. However, without throttling or token passing to limit the number of searches entering the network it seems like it ought to collapse *eventually*, albeit at a much higher load than without backoff. I've run sims up to a load of 50 with no problems - at 55 I started to get OOM errors for backoff alone, but I haven't looked into the causes yet. Cheers, Michael
