Hi, Today I had deadlock on several machines. Almost all processes stucked in [tx->tx_cpu[c].tc_lock]. Machines were helped only `reboot -n'. I've created new gzip-ed filesystem a few days ago. I didn't have any problems with ZFS before. System was built from svn://svn.freebsd.org/base/stable/8@215508. Machines have 24Gb RAM, 4 SATA 500Gb disks in raidz. zfs list: NAME USED AVAIL REFER MOUNTPOINT place 373G 982G 83.0G /place place/gzip 290G 982G 290G /place/gzip root 723M 1.25G 722M legacy var 9.90M 974M 9.77M /var loader.conf: ahci_load="YES" zfs_load="YES" vfs.zfs.arc_max="2G" vfs.zfs.cache_flush_disable="1" # default: 0 vfs.zfs.prefetch_disable="1" # default: 0 vfs.zfs.txg.timeout="5" # default: 30 vfs.zfs.zio.use_uma="0" # default: 0 (earlier was 1) Can anyone help me to find a problem? -- Andrey Zonov
