I'm not an expert, so take this with a grain of salt: > Adding RAM won't increase MBUFs, if I remember correctly. It is a kernel param, and can be tweaked by recompiling the kernel. (It may nowadays be possible to massage it by sysctl, or as a boot time param, but I'm not sure). So, you can tweak it without adding RAM. > As for your error: > > routed[1242]: Send mcast sendto(re5, 224.0.0.9.520): No buffer space available > > I've seen this when an ipfw rule prevented sending, like for a ping. Could it be a fw rule that is causing this? (Just grasping at straws). > Good luck, Gerald ----- Right now, it's just functioning as a 'core' router with NAT turned off. All interfaces have "Allow any protocol from anywhere to anywhere" rules on them. There are no other services enabled, not even dns forwarder or DHCP. Just pure routing and RIP. Looking at my edge firewall, I see MBUF usage like this: 738 /1845 which is very odd since that box also has 256MB RAM. The only difference is that my edge box has 2x128MB DIMMs and my core (problematic box) has a single 256MB DIMM. Are the MBUF values calculated randomly? Where do they come from?
