Yes, that's the function procstat -k uses to collect kernel stacks. This is similar to how "ps ... | grep ..." might show you the grep process. I couldn't see any obvious culprits among the functions blocked in ZFS routines. They were all blocked on a ZFS teardown lock, which is why I thi= nk the lock was leaked somehow. --=20 You are receiving this mail because: You are the assignee for the bug.=
