As others have said this happens when cache_mem > cache_dir.
The default example you have seen is for a version 2.4 to 3.0 Squid when
4MB cache_mem and 100MB disk cache was default. The current releases
have 256MB cache_mem and no disk by default. 256MB cache_mem > the
100MB demo config.
  We leave the warning around because nobody can be bothered removing it
and it does prove kind of helpful when you hit 32-bit wrap on a badly
built Squid.

But you only informed Squid with cache_dir that there was 100MB available.

Disk space is not Cache space. Cache space of a disk is the amount of
that disk space which was allocated to Squid using cache_dir.
