This is seen when Squid finds another object than it expected on the
disk. Such things might happen if you have had a unclean shutdown and
parts of swap.state has been lost. The effect is that squid complains
about the issue and falls back on processing the request as a cache
miss.

If you only receive one or two of them then there is no reason to worry.
If you receive a lot then it might be a good idea to have Squid rebuild
the index.

How:

1. Shut down Squid
2. Remove the cache_dir/swap.state* files
3. Start Squid again

Or you might ignore the issue. It should fix itself after a while unless
you have more unclean shutdowns or crashes.
