ZFS frequent config_sync events

Hi,
I have a server running on FreeBSD 10.2 amd64 with ZFS. I've noticed that ZFS sends every 5 seconds the event:

"!system=ZFS subsystem=ZFS type=misc.fs.zfs.config_sync pool_name=zp56F91D32 pool_guid=1478085706354093195"

Can anybody help me to understand the reason of this behavior?
P.S. sorry for my english.
 
I've seen already that man, but it does't help. I think the changes occur too frequent, e.g. on FreeBSD 10.2 with generic kernel and with zfs nothing occurs like that.

Hi Darkemon! I was thinking "What are the chances of someone having the same problem as me and posting about it on the same day" when I realised you posted this exactly a year ago :rolleyes:. I am getting the same message every five seconds:

devd: Processing event '!system=ZFS subsystem=ZFS type=misc.fs.zfs.config_sync pool_name=pool pool_guid=6193065107164661427'

It is preventing my pool from going to sleep, so it is really quite annoying.
This started happening after I upgraded from 10.1 to 11.

Did you manage to figure out the issue in the end?
Thanks!
