High CPU usage / ZFSNode syncing error

[hrenard]

What steps did you take and what happened:
The zfs-localpv-node is permanetly using 1 CPU.

What did you expect to happen:
Not using as much resources.

The output of the following commands will help us better understand what's going on:
Gist

Anything else you would like to add:
The process using the CPU:

/sbin/zfs list -s name -o name,guid,available -H -p

I suspect this error is related:
