I used to have the odd system hangup now and then during rsync-time.
When several host start sending their backups.

They all have gone since my last upgrade.
FreeBSD zfs.digiware.nl 10.2-STABLE FreeBSD 10.2-STABLE #3 r289060M: Fri

Even hangs attributed to using PCI-X bus freezes have gone.
uptime is now 54 days, where before it hardly got over 14 days.

So I think some things have changed for the better with recent patches.
