Hi Folks,
I've seen this panic recently, twice, on two companion servers running
Varnish-4.1.8 on FreeBSD-11.0
% varnishd -V
varnishd (varnish-4.1.8 revision d266ac5c6)
Copyright (c) 2006 Verdens Gang AS

% uname -a
FreeBSD hostname 11.0-RELEASE-p2 FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24

Unfortunately I do not have the full backtrace, but here's what I do have.

Varnishd process uptime was near-identical on both servers, and the panics
occurred at around the same time on both machines, which could potentially
indicate that the panic was caused either by a particular request, and/or
some resource-related issue. Time between panics was approximately 19
days.
I would welcome any advice about known possible causes for this particular
assertion failing!
Best Regards,
Mark Staudinger
