No. After lowering the zfs.arc everything appears fine. Here are my
parameters:

vfs.zfs.arc_min: 536870912
vfs.zfs.arc_max: 1073741824

Mem: 108M Active, 9934M Inact, 7570M Wired, 1565M Buf, 14G Free
ARC: 2214M Total, 838M MFU, 1099M MRU, 32K Anon, 6073K Header, 272M Other

Swap: 8192M Total, 8192M Free

My version is still 11.2-RELEASE-p7. I don't think it makes a big
difference...
