Bug? Barage of hits leads to failure creating worker threads / stats tracking

[Rafael Umann]

What about the cache size? have you decresead it?

Try running varnish with:

# varnishd -f /etc/varnish/default.vcl \
              -a 0.0.0.0:80 \
              -s file,/var/lib/varnish/varnish_storage.bin,50M \
              -T 0.0.0.0:6082 \
              -u varnish \
              -g varnish \
              -w 500,500,120 \
              -p lru_interval=900 \
              -p thread_pools=1 \
              -P /var/run/varnish/varnish.pid \
              -F"
