Any tips on how to improve the situation? am looking at the cvs logs to understand what was going on, but at first sight the code seems the same (functionally speaking) that fixed the problem in november. anyways, this problem was related with route entries changing/going away while the packet is stored in the dummynet (which does not last long, usually a few seconds). So, what is your underlying network structure, do you have multiple interfaces or routes that change etc ? cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
