We had same problem about a month ago on Intel D875PBZP motherboard with 5.1-RELEASE. It has a onboard Intel 10/100/1000 PRO (em) NIC. We left the machine idle for a month, since the machine is useless and we have plentiful other things to do. This week, we decide to use this machine for high-speed network test. Somehow, the machine just works without any change. I asked around and no one here says that they changed any thing. What I can suggest to you is to test a different NIC to see if the problem persists. If it is, then there is a kernel problem, otherwise, it is Intel problem. -Jin James West wrote: > The machine has 256Mb of RAM, 36Gb scsi drive and is a 1.3Ghz AMD cpu. > > I've switched MAXUSERS back to 0 now, right now before reboot my mbuf sysctl values read: > > # sysctl -a | grep mbuf > kern.ipc.mbuf_wait: 32 > kern.ipc.nmbufs: 260000 > > I'm stumped, stumped like a tree! > > James. > > ----- Original Message ----- > From: Lukas Ertl > Date: Wed, 16 Jul 2003 16:51:34 +0200 (CEST) > To: James West > Subject: Re: Major problem with "No buffer space available" errors > > > On Wed, 16 Jul 2003, James West wrote: > > > > > Hmm, kinda made that all confusing sounding, what i mean is i'm having > > > the problem with MAXUSERS set to 0 and also when its set to 512. > > > > You didn't tell us how much memory that box has.
