--- Comment #8 from Andriy Gapon <avg@FreeBSD.org> ---
(In reply to Steve Wills from comment #7)
First of all, I am not 100% sure if this is it. It could be. It's likely.


So, it looks like the lock is held because zfs_rezget -> ... ->
arc_get_data_impl is waiting for something in the ARC state.  Probably it's
waiting for the ARC size to go below its limit (arc_is_overflowing()).  So,=
 I
would look at the ARC variables and what the ARC reclaim thread is doing.
