Yes I do.... but this is a brand new zfsonroot with barely any data on it
and

sysctl -a | grep kern.openfiles
kern.openfiles: 68
root@:/master/builder # sysctl -a | grep kern.maxfiles
kern.maxfiles: 24600
kern.maxfilesperproc: 11095

the openfiles and maxfiles seems to be plenty, but im out of descriptors, i
used to see this back in the 4.x days when you could format
ufs with larger inodes, but zfs ??? really?
