https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275594 --- Comment #108 from Peter Much <pmc@citylink.dinoex.sub.org> --- My main workhorse (all purpose server, 48 GB, 5000+ threads) is also not affected at all. But everything else here is.=20 There are also cases where nothing really bad happens, but something is wro= ng nevertheless (here a small server 4 GB ram for my offsite backup, does not = much otherwise): operator@pole:~ $ ps axH | egrep "prune|dummynet" 0 - DLs 0:01.52 [kernel/arc_prune] 0 - DLs 23:29.91 [kernel/dummynet] This is after I installed the patches. Before that, the compute on arc_prune was about the same as on dummynet (dummynet is the firewall, that should be mostly unchanging) - so while no malfunction yet, still lots of wasted cpu cycles. --=20 You are receiving this mail because: You are the assignee for the bug.=
