hi all, I was extracting a 8GB tar and encountered this panic. the system was just installed last week with Solaris 10 update 3 and the latest recommended patches as of June 26. I can provide more output from mdb, or the crashdump itself if it would be of any use. any ideas what''s going on here? # uname -a SunOS fang 5.10 Generic_125101-09 i86pc i386 i86pc # mdb -k unix.0 vmcore.0 Loading modules: [ unix krtld genunix specfs dtrace uppc pcplusmp ufs ip sctp usba fcp fctl nca md lofs zfs random nfs sppp crypto ptm fcip cpc logindmux ] > ::status debugging crash dump vmcore.0 (32-bit) from fang operating system: 5.10 Generic_125101-09 (i86pc) panic message: BAD TRAP: type=e (#pf Page fault) rp=d4ab09d4 addr=20 occurred in module "zfs" due to a NULL pointer dereference dump content: kernel pages only > *panic_thread::findstack -v stack pointer for thread d490d600: d4ab08d0 d4ab09d4 0xd4ab08f4() d4ab0a30 zap_leaf_lookup+0x25(ebe7bc80, d4ab0bf0, 0, ea7a6950, d4ab0a60, d4ab0bf0) d4ab0a9c fzap_lookup+0x88(ebe7bc80, d4ab0bf0, 8, 0, 1, 0) d4ab0ad0 zap_lookup+0xb0(d4e02f48, 209ce, 0, d4ab0bf0, 8, 0) d4ab0b28 zfs_dirent_lock+0x23e(d4ab0b58, d82d8cd0, d4ab0bf0, d4ab0b54, 6) d4ab0b5c zfs_dirlook+0x9b(d82d8cd0, d4ab0bf0, d4ab0d30) d4ab0b84 zfs_lookup+0x6f(e219fd80, d4ab0bf0, d4ab0d30, d4ab0da0, 1, d3a65c00) d4ab0bc0 fop_lookup+0x2c(e219fd80, d4ab0bf0, d4ab0d30, d4ab0da0, 1, d3a65c00) d4ab0d38 lookuppnvp+0x295(d4ab0da0, 0, 0, d4ab0e50, 0, d3a65c00) d4ab0d70 lookuppnat+0xe8(d4ab0da0, 0, 0, d4ab0e50, 0, 0) d4ab0e58 vn_createat+0x9f(8090840, 0, d4ab0e98, 1, 80, d4ab0f00) d4ab0f0c vn_openat+0x323(8090840, 0, 2502, 180, d4ab0f68, 0) d4ab0f6c copen+0x24f() d4ab0f84 open64+0x1d() d4ab0fac sys_sysenter+0x100()
