https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D203906 --- Comment #9 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to emz from comment #8) Run kgdb and check what thread owns spa_namespace_lock. The switch to that thread and get its backtrace. That's in addition to capturing procstat -kk -a. If you can afford some down time, it may also be useful to trigger a kernel panic and save a crash dump. The crash dump is most useful when you have debugging symbols for the kernel and modules. --=20 You are receiving this mail because: You are the assignee for the bug.=
