It means that Squid opened up a disk file to serve a cache hit, but it
found that the stored object doesn't match what the user's request.
Squid stores the MD5 digest of the URL at the start of each disk file.
When the file is opened, Squid checks that the disk file MD5 matches
the MD5 of the URL requested by the user. If they don't match, the
warning is printed and Squid forwards the request to the origin

You probably do not need to worry about this warning. It means that
Squid is recovering from a corrupted cache directory.
