I am wondering if network problems may have something to do with my problem. The last time it stopped responding there was major network problems right before it stopped. I also had a non SMP box stop responding during bad network problems. On this box I was able to log in after I redirected all traffic to another box. When I checked netstat -m, mbuf clusters had peaked at 4608 which is usually only around 2000 mbufs. When there is lots of packet loss is it possible to eat up all mbufs? Should I beef up mbufs more in case of network problems? Thanks, Brian ## Here is my dmesg of SMP box FreeBSD 4.2-RELEASE #0: Tue May 8 11:32:54 PDT 2001 brianc@ver05.essoc.com:/usr/src/sys/compile/ESSOC Timecounter "i8254" frequency 1193182 Hz CPU: Pentium III/Pentium III Xeon/Celeron (933.07-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x686 Stepping = 6 Features=0x387fbff real memory = 1073676288 (1048512K bytes) config> di sn0 config> di lnc0 config> di ie0 config> di fe0 config> di ed0 config> di cs0 config> q avail memory = 1040588800 (1016200K bytes) Programming 16 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 16 pins in IOAPIC #1 IOAPIC #1 intpin 0 -> irq 2 IOAPIC #1 intpin 1 -> irq 11 IOAPIC #1 intpin 2 -> irq 9 IOAPIC #1 intpin 3 -> irq 10 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 3, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 0, version: 0x00040011, at 0xfee00000 io0 (APIC): apic id: 4, version: 0x000f0011, at 0xfec00000 io1 (APIC): apic id: 5, version: 0x000f0011, at 0xfec01000 Preloaded elf kernel "kernel" at 0xc0440000.
