This seems to have been mentioned in the beginning of April with no clear resolution. A few kernel options mentioned in the posts: --- cpu I686_CPU maxusers 512 options NMBCLUSTERS=16384 options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O --- This is a system with 1 GB of RAM. Network card is: fxp0: port 0xccc0-0xccff mem 0xf9000000-0xf90fffff,0xf9100000-0xf9100fff irq 10 at device 8.0 on pci1 What's wrong? There definitely should be enough buffers. Also: userspace froze earlier today for some odd reason; ping and traceroute responded, ipfw worked, tcp connection could be established but the daemon listening to the port never replied. Nothing in the log or the console. Ideas? Please Cc:. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems. Networks.
