Hi Carl,
Quoting: "You do not need to worry about this warning. It means that Squid is double-checking that the disk file matches what Squid thinks should be there, and the check failed. Squid recovers and generates a cache miss in this case."
If the issue persists after extended usage, it might indicate a bug in Squid's cache handling.
a quick search led me to https://wiki.squid-cache.org/SquidFaq/InnerWorkings#what-does-swapin-md5-mismatch-mean

We updated from Squid 5.9 to Squid 6.5, and then immediately started
seeing many of these new errors in the cache.log:
2023/12/08 23:26:52 kid1| ERROR: Failed to unpack Store entry metadata:
swap meta MD5 mismatch
exception location: SwapMetaIn.cc(89) CheckSwapMetaKey
current master transaction: master3394333
Can anyone suggest what these errors might mean? I looked at the source
code line indicated, but I couldn't understand what the issue might be.
Thanks.
