Last week I setup an 4.6 i386 OpenBSD server. The hardware is Dell Poweredge 1850 with 2GB RAM. Its fully updated 4.6 stable.
In only a few days it has twice hung with the error on screen: uvm_mapent_alloc: out of static map entries I have looked on the web and found various OpenBSD maillist archive references to this but the impression is that this was fixed ages ago. The server should be a very lightly used mail relay running exim, ssh and nothing much else. I certainly dont want to "randomly push buttons": http://kerneltrap.org/mailarchive/openbsd-misc/2008/5/16/1842014 but 2 years ago this seemed "under control": http://kerneltrap.org/mailarchive/openbsd-misc/2008/5/16/1841134 "But it's not really alarming, unless it continues to print that continuously." Its not doing it continuously - just once and then hang. Below is dmesg output. Please let me know if i can provide any more useful information. Many thanks, Alastair Johnson ==================== [[email protected] /etc]# dmesg OpenBSD 4.6-stable (GENERIC) #0: Thu Apr 22 22:41:04 BST 2010 r...@relayb:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Xeon(TM) CPU 3.20GHz ("GenuineIntel" 686-class) 3.20 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,CNXT-ID,CX16,xTPR real mem = 2146795520 (2047MB) avail mem = 2067058688 (1971MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 01/09/06, BIOS32 rev. 0 @ 0xffe90, SMBIOS rev. 2.3 @ 0xf9920 (87 entries) bios0: vendor Dell Computer Corporation version "A05" date 01/09/2006 bios0: Dell Computer Corporation PowerEdge 1850 acpi0 at bios0: rev 0 acpi0: tables DSDT FACP APIC SPCR HPET MCFG acpi0: wakeup devices PCI0(S5) PALO(S5) PBLO(S5) VPR0(S5) PBHI(S5) VPR1(S5) PICH(S5) 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 199MHz cpu at mainbus0: not configured ioapic0 at mainbus0: apid 2 pa 0xfec00000, version 20, 24 pins ioapic0: misconfigured as apic 0, remapped to apid 2 ioapic1 at mainbus0: apid 3 pa 0xfec80000, version 20, 24 pins ioapic1: misconfigured as apic 0, remapped to apid 3 ioapic2 at mainbus0: apid 4 pa 0xfec83000, version 20, 24 pins ioapic2: misconfigured as apic 0, remapped to apid 4 acpihpet0 at acpi0: 14318179 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 1 (PALO) acpiprt2 at acpi0: bus 2 (DOBA) acpiprt3 at acpi0: bus 3 (DOBB) acpiprt4 at acpi0: bus 4 (PBLO) acpiprt5 at acpi0: bus 8 (VPR0) acpiprt6 at acpi0: bus 5 (PBHI) acpiprt7 at acpi0: bus 6 (PXB1) acpiprt8 at acpi0: bus 7 (PXB2) acpiprt9 at acpi0: bus 9 (PICH) acpicpu0 at acpi0 bios0: ROM list: 0xc0000/0xb000!
