https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215513 --- Comment #5 from Michael Tuexen <tuexen@freebsd.org> --- By looking at your Details, your system is low on memory when the problem occurs. Can you just remove the KASSERT http://fxr.watson.org/fxr/source/netinet/tcp_sack.c#L474 and retest? I think if tcp_sackhole_insert in http://fxr.watson.org/fxr/source/netinet/tcp_sack.c#L446 returns NULL due to memory shortage, you run into the KASSERT.
