Basically we'd need the output of
optionally a second run with
varnishadm param.set debug +lurker
Trouble here is that, by default, the CLI interface will truncate the output
after 48k which is way too soon for any ban list of an order of magnitude as you
are seeing it.
The highest value currently accepted for the cli limit is just under 100MB,
which can be set using
varnishadm param.set cli_limit 99999999b
As a precaution, I would advise to raise the ping timeout with such huge CLI
varnishadm param.set cli_timeout 3600
This should be undone back to the default or whatever you had before after
gathering the data.
Feel free to send me the results via private email, bzip2 or xz compression
would probably be a good idea.
