Your question is asked frequently.

12.37 What does swapin MD5 mismatch mean?

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
server.

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