Hi John, Oops Sorry: FreeBSD -stable. Here is uname: FreeBSD lm741n.dyndns.org 4.7-STABLE FreeBSD 4.7-STABLE #0: Wed Dec 4 13:14:24 PST 2002 root@lm741n.dyndns.org:/usr/src/sys/compile/ROBKERN3 i386 There are no tuning specific tweeks to the kernel. Generic minus all the unneeded drivers plus audio and ipf. The Freenet server uses Java, which opens up alot of connections to other Freenet nodes. Its an anonymous encrypted distributed P2P network. And Java always seems to use an unusually high amount of memory even when the server isn't loaded heavily. I'm currently using Kaffe 1.0.7. It is much better in that respect than the linux-sun java distributions. In the case I run out of mbuf, I have a program which is inserting a web site into the network which contains 140 files plus index.html, anywhere from 3Mb to 20Mb per file. And the program splits up the files into fragments. That is one of the features of the network, splitfiles. Netstat -m shows 446 mbufs right now, but I think it gets much larger. Netstat shows also about 42 open connections to other servers and 39 connections to localhost. Thanks!! Rob.
