Hi there, I=92ve recently experienced two kernel panics on 8.4-RELEASE (within 2 = days of each other, and both around the same time of day oddly) with = ZFS. Sorry no dump available, but panic below. Any ideas where to start solving this? Will upgrading to 9 (or 10) solve = it? (Sorry for any errors, hand transcribed from a screenshot) panic:solaris asset: sa.sa_magic =3D=3D 0x2F505A (0x5112fb3d =3D=3D = 0x2f505a), file: = /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/= zfs_vfsops.c, line: 596 cpuid =3D 1 KDB: stack backtrace: #0 0xffffffffff8066cb96 at kdb_backtrace+0x66 #1 0xffffffffff8063925e at panic+0x1ce #2 0xffffffffff81292109 at assfail3+0x29 #3 0xffffffffff811157fe at zfs_space_delta_cb+0xbe #4 0xffffffffff8109ee12 at dmu_objset_userquota_get_ids+0x142 #5 0xffffffffff810a5e35 at dnode_sync+0xc5 #6 0xffffffffff8109cf3d at dmu_objset_sync_dnodes+0x5d #7 0xfffffffff8109d0c9 at dmu_objset_sync+0x169 #8 0xffffffffff810b446a at dsl_pool_sync+0xca #9 0xffffffffff810c4c3a at spa_sync+0x34a #10 0xffffffffff810d6959 at txg_sync_thread+0x139 #11 0xffffffffff8060dc7f at fork_exit+0x11f #12 0xffffffffff809a9c1e at fork_trampoline+0xe Uptime: 37d8h9m39s Cannot dump.
