Hello,

I am seeing this issue (high swap, arc not backing down) on two
jail/bhyve hosts running 11-STABLE r325275 and r325235 - which sounds
like it is earlier than the two patches you mention?

The two machines are at 98 and 138 days uptime, and both are currently
using more than 90% swap, and I've had to shut down non-critical stuff
because I was getting out-of-swap errors.

Just wanted to let everyone know, since I haven't seen any revisions as
early as r325275 in the "me too" posts here.

More information available on request.

Best regards,

Thomas Steen Rasmussen
