Solution 1:

It happens if someone manually plays with the disk cache, or if unlinkd
looses a race condition with the main squid process.

Squid is removing the index entries for such files at the point this is
reported to logs. There is nothing you need to do.

 

Solution 2:

Another reason of this problem is you have manually delected squid cache directory or directories and swap.state is still there. To solve this problem either rebuild cache from scratch, stop squid, remove cache directory and then start squid. It will first build fresh cache directories with new index files and the problem will resolved.
