Bug ID: 194513
Summary: zfs recv hangs in state kmem arena
Product: Base System
Version: 10.0-STABLE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: james-free...@jrv.org
I am having every attempt to replicate my ZFS pool fail due to "zfs recv"
blocking on "kmem arena".
This happens on two systems, and with both 10-STABLE and -CURRENT. It hangs
within the first 5TB, usually by 2TB, last night it failed after 4.35 MB.
I tried using a memstick image of -CURRENT made from the release/
process and this also hangs in "kmem arena".
The two tested systems have 16GB and 32GB of ECC RAM.
An uninvolved server of mine hung Friday night in state"kmem arena"
during periodic's "zpool history". After a reboot it did not hang
Saturday night.
The command that fails is
# zfs send -R BIGTEX/UNIX@snap | zfs recv -duvF BIGTOX
