Hello, [8.0 BETA-4/i386] I've got this panic when copying /usr on a new pool. It's 100% reproductible here with=20 tar cf - -C /usr . |=A0tar xpvf - -C /pool The panic occurs always with free() in the ZFS code. Unfortunaly I'm not able to save the dump but it's like : free() zfs_acl_node_free() zfs_acl_release_nodes() zfs_acl_free() zfs_zaccesss() zfs_freebsd_create() VOP_CREATE_APV() vn_open_read() vn_open() kern_openat() kern_open() open() syscall (open()) I saw this in the write() syscall too. /boot/loader.conf # ZFS vm.kmem_size=3D"512M" vm.kmem_size_max=3D"512M" vfs.zfs.arc_max=3D"40M" vfs.zfs.vdev.cache.size=3D"5M" and options KVA_PAGES=3D512 in my kernel Thanks in advance, regards.
