I run Nessus on this machine, with about 60 concurrent scans. It pushes the load average up as high as 20 for short periods of time, but overall is reasonably efficient. I have never had the box become unresponsive, let alone crash, under any load scenario. This morning, I ran my first scan on 7.2-stable, with Nessus 4.0. It lasted about 30 seconds before: Fatal trap 12: page fault while in kernel mode cpuid = 2; apic id = 06 fault virtual address = 0x1c fault code = supervisor read, page not present instruction pointer = 0x20:0xc07a4dac stack pointer = 0x28:0xee156ad4 frame pointer = 0x28:0xee156ad8 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 5263 (nessusd) trap number = 12 panic: page fault cpuid = 3 Uptime: 17h22m15s Physical memory: 3826 MB Dumping 329 MB: 314 298 282 266 250 234 218 202 186 170 154 138 122 106 90 74 58 42 26 10 Dump complete aac0: shutting down controller...done Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... cpu_reset: Stopping other CPUs -c On Thu, 14 May 2009, John Baldwin wrote: > Given that that is a single bit set, it could possibly be due to bad RAM. > Does your kernel have debug symbols?
