Squid is loading things that were provided to it without a Date header
out of the cache. It cannot handle that. Current versions will
synthesize a Date and Last-Modified if needed - which resolves most
cases of this problem. 3.3 does not have that improvement, it just
detects the bug and warns as it drops the object.

This can happen if you have refresh_pattern config options overriding
various of the caching headers. Squid can be fooled by those
override-*/ignore-* options into thinking it can re-use the object but
realy it lacks the headers to do so.

The warnings should gradually disappear as the old data in the cache
gets found and dropped. If it continues you should consider an upgrade.
You can find more up to date packages for CentOS at the links here:

Okay. Nothing that I'm aware of in the config.

There is a patch to silence it again, but if you are re-building you
might a well build the latest and do the upgrade.
