Hi,
I got such errors when I changed "cache_dir" parameters in squid.conf.
It's because the old directory tree isn't suitable for new parameters,
and as result
some objects aren't cached.
After reinit of cache directory (delete and recreate with squid -z)
the errors disappeared.

I've not touched cache_effective_user/group configuration. defaults to
nobody.
from squid.conf:
#Default:
