This is probably network-related and usually shows up when something is being done using the network (like NFS). The way to get around this would be to change the value of NMBCLUSTERS in your config file. NMBCLUSTERS is set at 256 by default, and increased to 512 when the GATEWAY option is active. To be very safe, you could add options NMBCLUSTERS=1024 to your config file, and recompile. This is reported to work with systems that crashed as soon as a large number of people (75+) were connected to it. I found this clip in Dave Burgesses' NetBSD, FreeBSD, and OpenBSD FAQ. Although for some strange reason I can't find where you can get it, but it shows up regularly on the BSD news groups and I believe I got it from FreeBSD-announce. -- =| Regards, =| FreeBSD ==> http://www.FreeBSD.org =| Kevin G.
