storage.memory.free_space and storage.memory.used_space

Hi,

I am using varnish-6.0.0 revision a068361dff0d25a0d85cf82a6e5fdaf315e06a7d
and the malloc storage.

My vcl_deliver looks like this:

sub vcl_deliver {
set resp.http.X-Varnish-Storage = {"Free: "} +
storage.memory.free_space + " Used: " + storage.memory.used_space + "
Happy? : " + storage.memory.happy;
}

I am confused because upon making a request to my varnish server,
storage.memory.free_space
is always equal to storage.memory.used_space * -1.

E.g if storage.memory.used_space is 150000.000 then
storage.memory.free_space is -150000.000.

Moreover, storage.memory.happy is always false.

This has been the case for the longest time. I'm pretty sure I had this
issue with Varnish 4, and maybe even earlier versions.

Am I doing something wrong? Or is this a bug?

Sincerely,
-Hugues

could it be that you are using unbounded Transient? If so, while it's
indeed a bit weird, it's more or less explained by the fact that the space
value is irrelevant anyway.

Hi Guillaume,

Indeed! This is the issue. An error in one of my script is passing -s
'memory=malloc, ' to Varnish, instead of a sane value.

Cheers,
