Running 9.1-PRERELEASE currently. Just set this server up, imported the pool from OpenIndiana 151 I believe it was. When I access (simply `ls`) certain files/directories, the system panics. These files have ACL properties set on them from the Solaris system. This system has 32gb of ram and only 8gb swap setup, so I do not currently have a kernel core dump. It's also practically a production machine, so I do not have much leeway in testing on it. backtrace: >From running ls(1): panic: avl_find() succeeded inside avl_add() avl_add+0x4b zfs_fuid_table_load+0x198 zfs_fuid_init+0x12c zfs_fuid_find_by_idx+0xc7 zfs_fuid_map_id+0x19 zfs_groupmember+0x16 zfs_zaccess_aces_check+0x196 zfs_zaccess+0xc6 zfs_freebsd_getattr+0x1c1 vn_stat+0x6a kern_statat_vnhook+0xf9 kern_statat+0x15 sys_lstat+0x2a amd64_syscall+0x540 At first I thought this was related to MAC / ugidfw, but I am able to reproduce with those not compiled in. FWIW, here is a backtrace from having that enabled: panic: avl_find() succeeded inside avl_add() avl_add+0x4b zfs_fuid_table_load+0x198 zfs_fuid_init+0x12c zfs_fuid_find_by_idx+0xc7 zfs_fuid_map_id+0x19 zfs_groupmember+0x16 zfs_zaccess_aces_check+0x196 zfs_zaccess+0xc6 zfs_freebsd_getattr+0x1c1 ugidfw_check_vp+0x6c mac_vnode_check_stat+0xa7 vn_stat+0x39 kern_statat_vnhook+0xf9 kern_statat+0x15 sys_stat+0x2a amd64_syscall+0x540 Is there some easy way to clear these ACL properties on the files? I do not need them. Any suggestions on how I might fix this or debug this further? Bryan
