Hi, I'm running squid stable 6 and I find that if I download the following file: http://trials.macromedia.com/pub/esd/activation/DreamweaverMX2004-en.zip from internet explorer but don't hit save then my mem_node count will grow and my process memory usage will grow. This isn't limited by the cache_mem directive and keeps growing until the full file is downloaded. As this is a 100MB file, squid will grow by 100MB. After the download is complete, the mem_node count will drop back down but the memory usage stays at over 100MB. Should I be expecting this behaviour? Should my memory usage also drop back down after the download is complete? Thanks, Graeme
