Hi, Installed OpenBSD 4.6 today.
# uname -a OpenBSD shitforbrains.tog 4.6 GENERIC#58 i386 The box is doing nothing but being a VPN endpoint using OpenVPN. My VPN works fine but periodically the tunnel blows up with: Dec 27 23:31:24 shitforbrains openvpn[28217]: write UDPv4: No buffer space available (code=55) Dec 27 23:31:37 shitforbrains last message repeated 33287 times I restart OpenVPN and the problem persists. Below are the characteristics of the box itself. PF also in use, can show the rules if needs be. I ran # ktrace - f /var/log/ktrace.out -tc openvpn --daemon --config /etc/openvpn/26c3.conf --script-security 2 And I have uploaded the output from kdump -f /var/log/ktrace.out > kdump.txt http://konundrum.org/kdump.txt (OpenVPN not running) # netstat -m 77 mbufs in use: 64 mbufs allocated to data 3 mbufs allocated to packet headers 10 mbufs allocated to socket names and addresses 64/332/6144 mbuf 2048 byte clusters in use (current/peak/max) 0/8/6144 mbuf 4096 byte clusters in use (current/peak/max) 0/8/6144 mbuf 8192 byte clusters in use (current/peak/max) 0/8/6144 mbuf 9216 byte clusters in use (current/peak/max) 0/8/6144 mbuf 12288 byte clusters in use (current/peak/max) 0/8/6144 mbuf 16384 byte clusters in use (current/peak/max) 0/8/6144 mbuf 65536 byte clusters in use (current/peak/max) 1012 Kbytes allocated to network (14% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines # dmesg OpenBSD 4.6 (GENERIC) #58: Thu Jul 9 21:24:42 MDT 2009 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) 4 CPU 1.60GHz ("GenuineIntel" 686-class) 1.60 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 real mem = 803762176 (766MB) avail mem = 767864832 (732MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 05/07/03, BIOS32 rev. 0 @ 0xfd760, SMBIOS rev. 2.31 @ 0xf03d0 (76 entries) bios0: vendor FUJITSU SIEMENS // Phoenix Technologies Ltd. version "4.06 Rev. 1.06.1386" date 05/07/2003 bios0: FUJITSU SIEMENS D1386 acpi0 at bios0: rev 0 acpi0: tables DSDT FACP APIC BOOT acpi0: wakeup devices PCI0(S4) AGPB(S4) PCIH(S4) USB1(S4) USB2(S4) USB3(S4) USB4(S4) AC97(S4) MC97(S4) KEYB(S4) PS2M(S4) COM1(S1) COM2(S1) 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 99MHz ioapic0 at mainbus0: apid 1 pa 0xfec00000, version 20, 24 pins acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 1 (AGPB) acpiprt2 at acpi0: bus 2 (PCIH) acpicpu0 at acpi0 acpibtn0 at acpi0: PWRB bios0: ROM list: 0xc0000/0xc800 0xe0000/0x4000!
