Hello. I have a couple of Supermicro servers which got the similar kernel panic = with all FreeBSD versions I tried since 6.4. Now I want to investigate into the problem. The servers get into panic with similar workload: file server with a lot = of files and connections. Web server software is nginx. File system is = UFS+GJOURNAL. Outgoing traffic on each server is ~10 MB/s. I think it is not software problem, because when I've installed Linux = with such configuration there were no kernel panics. Here is the short overview of the hardware: CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (2992.51-MHz K8-class CPU) Origin =3D "GenuineIntel" Id =3D 0xf65 Family =3D f Model =3D 6 = Stepping =3D 5 = Features=3D0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE= ,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=3D0xe59d<SSE3,DTES64,MON,DS_CPL,EST,TM2,CNXT-ID,CX16,xTPR,PDCM>= AMD Features=3D0x20100800<SYSCALL,NX,LM> AMD Features2=3D0x1<LAHF> TSC: P-state invariant real memory =3D 2147483648 (2048 MB) avail memory =3D 2054619136 (1959 MB) DMESG: http://lexasoft.ru/m/dmesg.txt CORE: http://lexasoft.ru/m/core.txt Fatal trap 1: privileged instruction fault while in kernel mode cpuid =3D 1; apic id =3D 01 instruction pointer =3D 0x20:0xffffff8040d2cc83 stack pointer =3D 0x28:0xffffff8040d2ca80 frame pointer =3D 0x28:0xffffff0060c0b740 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 9388 (nginx) trap number =3D 1 panic: privileged instruction fault cpuid =3D 1 Uptime: 17d15h48m49s Physical memory: 2032 MB Dumping 1485 MB: 1470 1454 1438 1422 1406 1390 1374 1358 1342 1326 1310 = 1294 1278 1262 1246 1230 1214 1198 1182 1166 1150 1134 1118 1102 1086 = 1070 1054 1038 1022 1006 990 974 958 942 926 910 894 878 862 846 830 814 = 798 782 766 750 734 718 702 686 670 654 638 622 606 590 574 558 542 526 = 510 494 478 462 446 430 414 398 382 366 350 334 318 302 286 270 254 238 = 222 206 190 174 158 142 126 110 94 78 62 46 30 14 (kgdb) #0 doadump () at pcpu.h:223 #1 0xffffffff80590c59 in boot (howto=3D260) at /usr/src/sys/kern/kern_shutdown.c:416 #2 0xffffffff8059108c in panic (fmt=3D0xffffffff80951fc4 "%s") at /usr/src/sys/kern/kern_shutdown.c:579 #3 0xffffffff80878fd8 in trap_fatal (frame=3D0xffffff0060c0b740, = eva=3DVariable "eva" is not available. ) at /usr/src/sys/amd64/amd64/trap.c:857 #4 0xffffffff808799ea in trap (frame=3D0xffffff8040d2c9d0) at /usr/src/sys/amd64/amd64/trap.c:644 #5 0xffffffff8085f983 in calltrap () at /usr/src/sys/amd64/amd64/exception.S:224 #6 0xffffff8040d2cc83 in ??
