A different panic this time (I've seen it before, but I couldn't get a crashdump that time). A common thread in all of these panics is that they all seem to involve operations on MFS filesystems. Even though the two UFS disk filesystems on the clients have the most read/write load, I don't think I've seen a panic involving them. /var: bad dir ino 24 at offset 0: mangled entry panic: ufs_dirbad: bad dir Debugger("panic") Stopped at Debugger+0x35: movb $0,in_Debugger.426 db> Here's the backtrace. #10 0xc01b1998 in panic (fmt=0xc03868e7 "ufs_dirbad: bad dir") at ../../kern/kern_shutdown.c:593 #11 0xc02ba91e in ufs_dirbad (ip=0xc1d6bb00, offset=0, how=0xc0386890 "mangled entry") at ../../ufs/ufs/ufs_lookup.c:641 #12 0xc02ba11b in ufs_lookup (ap=0xd6853d24) at ../../ufs/ufs/ufs_lookup.c:291 #13 0xc02bf1bd in ufs_vnoperate (ap=0xd6853d24) at ../../ufs/ufs/ufs_vnops.c:2422 #14 0xc01dab16 in vfs_cache_lookup (ap=0xd6853d7c) at vnode_if.h:77 #15 0xc02bf1bd in ufs_vnoperate (ap=0xd6853d7c) at ../../ufs/ufs/ufs_vnops.c:2422 #16 0xc01ddaf5 in lookup (ndp=0xd6853ed4) at vnode_if.h:52 #17 0xc01dd5e0 in namei (ndp=0xd6853ed4) at ../../kern/vfs_lookup.c:153 #18 0xc01e61b5 in vn_open (ndp=0xd6853ed4, fmode=1, cmode=420) at ../../kern/vfs_vnops.c:138 #19 0xc01e21c8 in open (p=0xd6796a00, uap=0xd6853f80) at ../../kern/vfs_syscalls.c:1006 #20 0xc032c7fd in syscall2 (frame={tf_fs = 47, tf_es = 47, tf_ds = 47, tf_edi = 4, tf_esi = 672135776, tf_ebp = -1077945320, tf_isp = -695910444, tf_ebx = 672062116, tf_edx = 672135776, tf_ecx = 16, tf_eax = 5, tf_trapno = 7, tf_err = 2, tf_eip = 671971036, tf_cs = 31, tf_eflags = 647, tf_esp = -1077945364, tf_ss = 47}) at ../../i386/i386/trap.c:1167 #21 0xc031dab5 in Xint0x80_syscall () #22 0x804a987 in ??
