2418 may very well be responsible. You could try working around this by adding more worker threads to your pools. That would postpone the deadlock to higher concurrent traffic. And possibly increase the thread reserve as well. > Let us know if we can help to solve these problems. I'm afraid we already have a consistent reproducer, so I guess all that remains is that we (Dag) roll up our (his) sleeves and do something about it. Joke aside, we've looked at it then but it's not an easy task. In my previous message I said: > so ignore varnish-modules for now, please be aware of this before > choosing one. What I really meant was: > so ignor[ing] varnish-modules for now, please be aware of this before > choosing one. In other words, once varnish-modules supports 6.1, please consider that 6.0 is an LTS series before you pick your target. Not that there is anything wrong about picking 6.1 if you are planning to periodically have major upgrades (I wouldn't recommend staying on an unmaintained branch once it reaches EOL).
