It's highly reproducible, like 1 of 5 zfs renames leads to lockup. I plan to schedule a maintenance time on our production site, reproduce this and get the procstat -kk of the zfs rename process that you requested in 226499. --=20 You are receiving this mail because: You are the assignee for the bug.=
