"Heavy" is about 400-500 kbytes/second pushed out through the NIC from 170-200 simultaneous apache processes. The box runs just apache and stronghold, with database served from a UP PIII 550 machine that's separate. NIC is a 3COM 3C905B. Kernel is customized, but maxusers is set to 128 with NMBCLUSTERS to 8192. We never get close to using all the clusters. Motherboard is a Supermicro P6SBU with 1GB ECC RAM. I've pushed more traffic than this on a UP machine, with a slower processor and less memory and the same NIC. That leaves potential hardware/configuration problems being related to: DPT controller (I've used this several times, though not an a 3.2-era machine) 1GB memory (first time with this much memory in a box) Dual processor -Troy Cobb Circle Net, Inc. http://www.circle.net > -----Original Message----- > From: Doug [mailto:Doug@gorean.org] > Sent: Saturday, August 07, 1999 5:06 PM > To: tcobb@staff.circle.net > Cc: freebsd-stable@FreeBSD.ORG > Subject: Re: continued crashes with 3.1-Stable > > > tcobb@staff.circle.net wrote: > > > > I think the problem is the SMP.
