The issue is not that memory is being pre-allocated to the forwarding / flow process. This is expected and required to function. The issue is that when things switched to flow support the memory usage went *way* up, and even when you convert to packet mode it is not reduced. If adding flow support causes the forwarding daemon to grow a couple hundred megs than going back to packet should free most of that memory. A 1GB J that used to run with at least a few hundred megs available now has < 40 megs free... -- ------------------------------------------------------------------------ Christopher E.
