Hi all I have only just seen this, and thought someone may be able to help.
On heavy IO activity, my Solaris 11 Express box hosting a ZFS data pool crashes. It seems to show page faults in several things, including nfsd, sched, zpool-tank and automountd. I get the following in the logs: Mar 17 15:28:17 zippy unix: [ID 836849 kern.notice] Mar 17 15:28:17 zippy ^Mpanic[cpu1]/thread=ffffff01d017f400: Mar 17 15:28:17 zippy genunix: [ID 335743 kern.notice] BAD TRAP: type=e (#pf Page fault) rp=ffffff0008925c40 addr=fffff701e470feb0 occurred in module "genunix" due to an illegal access to a user address Mar 17 15:28:17 zippy unix: [ID 100000 kern.notice] Mar 17 15:28:17 zippy unix: [ID 839527 kern.notice] automountd: Mar 17 15:28:17 zippy unix: [ID 753105 kern.notice] #pf Page fault Mar 17 15:28:17 zippy unix: [ID 532287 kern.notice] Bad kernel fault at addr=0xfffff701e470feb0 Mar 17 15:28:17 zippy unix: [ID 243837 kern.notice] pid=598, pc=0xfffffffffba0f3e4, sp=0xffffff0008925d30, eflags=0x10297 Mar 17 15:28:17 zippy unix: [ID 211416 kern.notice] cr0: 8005003b<pg,wp,ne,et,ts,mp,pe> cr4: 6f8<xmme,fxsr,pge,mce,pae,pse,de> Mar 17 15:28:17 zippy unix: [ID 624947 kern.notice] cr2: fffff701e470feb0 Mar 17 15:28:17 zippy unix: [ID 625075 kern.notice] cr3: 13fefb000 Mar 17 15:28:17 zippy unix: [ID 625715 kern.notice] cr8: c Mar 17 15:28:17 zippy unix: [ID 100000 kern.notice] Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] rdi: ffffff01cd1d5608 rsi: 0 rdx: ffffff01d017f400 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] rcx: 1 r8: ffffff01f4d0b040 r9: ffffff01f4da7c40 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] rax: 0 rbx: ffffff01cd1d5608 rbp: ffffff0008925dc0 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] r10: ffffff01cb227588 r11: ffffff01de01aa40 r12: ffffff01cd1d55f8 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] r13: fffff701e470feb0 r14: ffffff01e7177ec0 r15: fffff701e470feb0 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] fsb: 0 gsb: ffffff01cecc4080 ds: 4b Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] es: 4b fs: 0 gs: 1c3 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] trp: e err: 0 rip: fffffffffba0f3e4 Mar 17 15:28:17 zippy unix: [ID 592667 kern.notice] cs: 30 rfl: 10297 rsp: ffffff0008925d30 Mar 17 15:28:17 zippy unix: [ID 266532 kern.notice] ss: 38 Mar 17 15:28:17 zippy unix: [ID 100000 kern.notice] Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925b20 unix:die+dd () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925c30 unix:trap+1799 () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925c40 unix:cmntrap+e6 () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925dc0 genunix:dnlc_purge_vfsp+8c () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925e10 genunix:dounmount+35 () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925e60 genunix:umount2_engine+5c () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925ec0 genunix:umount2+145 () Mar 17 15:28:17 zippy genunix: [ID 655072 kern.notice] ffffff0008925f10 unix:brand_sys_syscall32+17a () Mar 17 15:28:17 zippy unix: [ID 100000 kern.notice] Mar 17 15:28:17 zippy genunix: [ID 672855 kern.notice] syncing file systems...
