plenty of memory, but system us intensively swapping

Hello, I have a recent FreeBSD 11-STABLE which is mainly used as an iSCSI target. The system has 64G of RAM but is swapping intensively. Yup, about of half of the memory is used as ZFS ARC (isn't capped in loader.conf), and another half is eaten by the kernel, but it oly uses only about half

Where is my memory on 'fresh' 11-STABLE? It should be used by ARC, but it is not used for it anymore.

I have server which is mostly torrent box. It uses ZFS and equipped with 16GiB of physical memory. It is running 11-STABLE (r339914 now). I've updated it to r339914 from some 11.1-STABLE revision 3 weeks ago. I was used to see 13-14GiB of memory in ZFS ARC and it was Ok. Sometimes it "locks"
