Hey there. I have a server running FreeBSD 13.0-RELEASE, with a large =

may not be related.

Any idea what I should be looking for, and if there=E2=80=99s any way to =

Ps, apologies for the rapid secondary email, but I forgot to mention =
something important. A =E2=80=9Czpool status tank=E2=80=9D is also =
hanging. So, it=E2=80=99s not just FS operations that are stuck.
