https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209475 --- Comment #34 from commit-hook@freebsd.org --- A commit references this bug: Author: kp Date: Sun Mar 18 11:26:07 UTC 2018 New revision: 331117 URL: https://svnweb.freebsd.org/changeset/base/331117 Log: MFC r329950: pf: Cope with overly large net.pf.states_hashsize If the user configures a states_hashsize or source_nodes_hashsize value we may not have enough memory to allocate this. This used to lock up pf, because these allocations used M_WAITOK. Cope with this by attempting the allocation with M_NOWAIT and falling bac= k to the default sizes (with M_WAITOK) if these fail.
