Today, I noticed some sites were not loading and was getting "connection refused error". checked the cache.log and noticed squid was restarting due to 2010/10/08 15:41:01| WARNING: redirector #17 (FD 24) exited 2010/10/08 15:41:01| WARNING: redirector #15 (FD 22) exited 2010/10/08 15:41:01| WARNING: redirector #10 (FD 17) exited 2010/10/08 15:41:01| WARNING: redirector #13 (FD 20) exited 2010/10/08 15:41:01| WARNING: redirector #12 (FD 19) exited 2010/10/08 15:41:01| WARNING: redirector #6 (FD 13) exited I shutdown squid and after 5 minutes restarted it again and now i get the following: 2010/10/08 15:44:30| WARNING: 1 swapin MD5 mismatches 2010/10/08 15:44:30| could not parse headers from on disk structure! 2010/10/08 15:44:42| could not parse headers from on disk structure! 2010/10/08 15:44:42| could not parse headers from on disk structure! 2010/10/08 15:45:10| could not parse headers from on disk structure! 2010/10/08 15:45:13| could not parse headers from on disk structure! 2010/10/08 15:45:16| could not parse headers from on disk structure! 2010/10/08 15:45:25| could not parse headers from on disk structure! 2010/10/08 15:45:26| could not parse headers from on disk structure! 2010/10/08 15:45:29| could not parse headers from on disk structure! Don't know what causes it but, I'm suspecting some cache files are corrupted. I had a power outage yesterday and maybe it caused that. How can I fix that error? Thanks in advanced for your help.
