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 Oct 9 11:46:21 CEST 2015 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. --WjW
