5.1.3: unexplained lockup during several minutes

Hello,

I'm struggling figuring out a problem that occurs rarely, and random
times, on different machines with the same setup (so excluding hardware
problems). This leads to varnish not answering any requests anymore for
several minutes.

Running on a 8 CPU amazon EC2 instance with the following parameters:
varnishd -F -f /etc/varnish/config.vcl -I /etc/varnish/settings.cli -n varnishd -s malloc,8G -a 127.0.0.1:8080,PROXY

When the lockup occurs, the loadavg increases from 0 to about 20 and 2
out of 8 CPUs are 100% in iowait mode (maybe because I use 2 threadpools ?)

There is plenty of free memory, and no disk IO activity, nothing in
dmesg. Apart from varnish, there's haproxy and a couple of varnishlog
and other monitoring tools running on these machines.

The 2 non-default settings I set are:
thread_pool_min 1000
timeout_idle 45

On specificity: the backends set quite short TTLs on the objects they
produce (less than 10s), but grace time is set to 300s, so I was
wondering is there might be a side-effect with the Transient store.

Any hint or clue would be much welcome !

Below are the log messages and the output of varnishstat -1:
