Hello, we are seeing occasional zfs hangs on our file servers. The symptoms = are these: - no NFS response - =91zpool status=92 works and shows no errors, but =91zfs list=92 hangs - ls on the mounted filesystems hangs as well - kernel version is FreeBSD 10.0-STABLE #0 r265916, GENERIC According to https://wiki.freebsd.org/AvgZfsDeadlockDebug this looks = like a possible deadlock. Running processes: https://www.badexample.net/tmp/ps-aux.txt procstat -kk -a output: https://www.badexample.net/tmp/procstat.txt Kind regards, Walter Heukels CloudVPS
