Same deadlock remains. Ok, to track this down I need the following: Uncomment 'CFLAGS+=3D-DDEBUG=3D1' line in sys/modules/zfs/Makefile. Add the following lines to your kernel config: options WITNESS options WITNESS_SKIPSPIN options INVARIANTS options INVARIANT_SUPPORT options DEBUG_VFS_LOCKS options DEBUG_LOCKS options KDB options DDB Recompile your kernel and modules and reboot. Once the deadlock occur, enter DDB and send me the output of: ps show alllocks show lockedvnods show allchains alltrace Thanks. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
