Too much RAM used for wired memory

My PC uses too much wired memory after few days.
After two weeks of uptime, wired memory usage is more than 50% of my RAM
(17G Wired, 32 GB of physical RAM)
PC is used with ZFS, 1 VM (bhyve, 1 CPU, 256 MB of RAM, passthru PCIe LAN
card, pinned to 1 phy CPU, priority/nice is -10), Xorg, multiple Firefox
instances (one used for playing videos), work in shell (zsh, tmux, vim,
...), GUI filemanager, GUI PDF reader and sometimes with KiCAD and/or WINE.

Even after stopping VM, all programs, Xorg, tmux, dbus, avahi, moused,
cups, other daemons, exporting non-root ZFS pool, going to single user mode
- wired memory still doesn't decrease

man vmstat shows:
-z      Report on memory used by the kernel zone allocator, uma(9), by zone.

Is that the same as wired memory?

How can I see what exactly is using that much of wired memory?
What metrics should I use to pinpoint issue? vmstat? sysctl counters?
