It's a quite= well equipped SBC with 2GB RAM and four SATA channels. I know the issues w= ith ZFS on 32 bit platforms and fiddled already with the suggestions from h= ttps://wiki.freebsd.org/ZFSTuningGuide#i386. Still I just don't get it runn= ing. No matter what kmem_size or how small the ARC - it only extends the time ZF= S works until the whole machine hangs. There are no OOM warnings or any err= or messages at all. First the ZFS processes stop working while everything e= lse still seems to respond, then no new processes can be started until ever= ything just freezes. I tried 13/release and 13/stable - no difference. I think the memory management was considerably changed with OpenZFS. So wha= t of this old vm adjustment stuff is still relevant? What could be the next= debugging steps? Could anybody with insights lend me a hand? Regards, Soeren
