hum…
May 12 03:00:48 freebsd kernel: pid 13188 (rsync), jid 0, uid 0, was killed: failed to reclaim memory
you mean 4GB of RAM is not enough to transfer a couple of TB from #ZFS to ZFS using rsync on #FreeBSD?
I am used to "raise your openfiles limit", not "no NAS server with less than 32GB RAM thank you"… 🤷♂️

Ok, I probably get a thing here... I applied a temporary sysctl vfs.zfs.arc_max=200000000 to keep ARC usage a bit lower. This does the trick with smaller data subset. Gonna retry the whole big data set when the last smaller rsync test is done. ARC is supposed to be giving memory back when needed by someone else. It doesn't seem to work well enough on my computer©
