i was troubleshooting some work i'm doing with python, and ran fstat(1), as root, with no arguments.
machine is rack-mounted in a data center, far away from me, but with an assist, i was able to get the following screen cap: http://imgur.com/kdbaW.jpg here's the text included therein: uvm_fault(0xd8227010, 0x0, 0, 1) -> e kernel: page fault trap, code=0 Stopped at fill_file2+0x346: movl 0x44(%edx),%eax ddb{0}> unfortunately, due to some problems on my end, i wasn't able to get a remote console. after the machine came back up, i ran fstat as an unprivileged user, again with no arguments and the host crashed again. no screen cap/scrape from the 2nd lock, however. as soon as i get my KVM/java nonsense sorted, i'll be able to test further. but for now, i'll not be running fstat(1) again, but i have a gut feeling this is symptomatic of something else, that probably needs attention sooner rather than later. i saw in the archive that Stuart Henderson posted something similar a while back, but didn't see any follow-up. any hints to get me looking in the right direction? i'm running 4.6-STABLE, SMP kernel. dmesg attached: OpenBSD 4.6 (build) #5: Thu Nov 12 10:28:47 EST 2009 [email protected]:/usr/local/build cpu0: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz ("GenuineIntel" 686-class) 2.41 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,CX16,xTPR real mem = 2145677312 (2046MB) avail mem = 2065956864 (1970MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 09/17/07, BIOS32 rev. 0 @ 0xf0010, SMBIOS rev. 2.5 @ 0xfd620 (27 entries) bios0: vendor American Megatrends Inc. version "080012" date 09/17/2007 bios0: PCCHIPS P17G acpi0 at bios0: rev 0 acpi0: tables DSDT FACP APIC MCFG OEMB HPET acpi0: wakeup devices P0P2(S4) P0P1(S4) WOL_(S4) PS2K(S3) PS2M(S3) UAR1(S4) EUSB(S4) MC97(S4) USB0(S3) USB1(S3) USB2(S3) USB3(S3) P0P4(S4) P0P5(S4) P0P6(S4) P0P7(S4) P0P8(S4) P0P9(S4) SLPB(S4) PWRB(S4) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: apic clock running at 266MHz cpu1 at mainbus0: apid 1 (application processor) cpu1: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz ("GenuineIntel" 686-class) 2.40 GHz cpu1: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,CX16,xTPR ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 20, 24 pins acpihpet0 at acpi0: 14318179 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 1 (P0P1) acpiprt2 at acpi0: bus -1 (P0P4) acpiprt3 at acpi0: bus -1 (P0P5) acpiprt4 at acpi0: bus -1 (P0P6) acpiprt5 at acpi0: bus -1 (P0P7) acpiprt6 at acpi0: bus -1 (P0P8) acpiprt7 at acpi0: bus -1 (P0P9) acpicpu0 at acpi0: PSS acpicpu1 at acpi0: PSS acpitz0 at acpi0: critical temperature 60 degC acpibtn0 at acpi0: SLPB acpibtn1 at acpi0: PWRB bios0: ROM list: 0xc0000/0xae00!
