There is no auth to begin with.
Public has no meaning on these responses.
The HTTP/1.0 Expires: timestamp check is skipped (it always says +6hrs
from now on every fresh request anyway), leaving Squid with only the
max-age=21600 value to work from.

Good. Shows it is probably not your refresh pattern at all causing the
problem.
Where else in the config do you have anything mentioning cache or object
limitations (size etc)?
