This causes the message to decline as things get fixed. It may last a week or more to completely go, but should have an exponential decline as cleanup progresses. Are they noticeably decreasing already? Another potential cause is an upgrade of Squid where a disk format bug was added or fixed between the two versions. Or 32-bit -> 64-bit upgrade to the build or hardware. This would churn through the whole previous cache instead of just a small selection of corrupted files. If the warnings are not decreasing with time you may need to enable the store.log and check the timestamps for creation/release for some of the reported files. Any which are created by the current process then fail to read back need closer inspection. Things to consider that will impact this are: since you last re-started Squid has there been an OS kernel update? a squid binary change? a libc update? an ntp binary update (timestamp sizes)? a filesystem change? crypto library update (MD5)? Any one of those could stay hidden on the system until a restart of the box or Squid brings up the new software linkages.
