Hi,
I just want to report a similar issue here with 11.2-RELEASE-p8.
The affected machine has 64 GB ram and does daily backups from several
machines in the night, at daytime there a parallel runs of clamav on a
specific dataset.
One symtom is basic I/O-performance: After upgrading from 11.1 to

After several days, ARC is even smaller, but Wired is the same:
Mem: 88M Active, 904M Inact, 29G Wired, 1121M Free
ARC: 13G Total, 5288M MFU, 6937M MRU, 2880K

It works for me :-)

Hi!
Long story short: 11.2-STABLE/amd64 r335757 leaked over 4600MB kernel wired
memory over 81 days uptime
out of 8GB total RAM.
Details follow.
I have a workstation running Xorg, Firefox, Thunderbird, LibreOffice and
occasionally VirtualBox for single VM.
It has two identical 320GB HDDs
