Is there a new way to set arc.max in 15-current?
It's no longer settable (except to "0") in main-n265801 (Oct 7th)
while multiuser.
# sysctl vfs.zfs.arc.max=8589934592
vfs.zfs.arc.max: 0

Try reducing your arc.max by an order of 10. This suggests that it's
probably failing in param_set_arc_max() in the val >= arc_all_memory()
comparison..
Hi, thanks for replying. Sadly, your suggestion doesn't work in this case:
