Hi. What are the reasons of squid rebuilding it's cache? Sometimes after startup sometimes during work it starts to rebuild cache. I see it in cahce.log: 2009/01/16 09:30:24| Starting Squid Cache version 2.6.STABLE6 for x86_64-redhat-linux-gnu... 2009/01/16 09:30:24| Process ID 2625 2009/01/16 09:30:24| With 1024 file descriptors available 2009/01/16 09:30:24| Using epoll for the IO loop 2009/01/16 09:30:24| DNS Socket created at 0.0.0.0, port 60302, FD 5 2009/01/16 09:30:24| Adding domain mydomain.com from /etc/resolv.conf 2009/01/16 09:30:24| Adding nameserver 22.179.1.11 from /etc/resolv.conf 2009/01/16 09:30:24| Adding nameserver 22.179.1.15 from /etc/resolv.conf 2009/01/16 09:30:24| User-Agent logging is disabled. 2009/01/16 09:30:24| Referer logging is disabled. 2009/01/16 09:30:24| Unlinkd pipe opened on FD 10 2009/01/16 09:30:24| Swap maxSize 16777216 KB, estimated 1290555 objects 2009/01/16 09:30:24| Target number of buckets: 64527 2009/01/16 09:30:24| Using 65536 Store buckets 2009/01/16 09:30:24| Max Mem size: 393216 KB 2009/01/16 09:30:24| Max Swap size: 16777216 KB 2009/01/16 09:30:24| Local cache digest enabled; rebuild/rewrite every 3600/3600 sec 2009/01/16 09:30:24| Store logging disabled 2009/01/16 09:30:24| Rebuilding storage in /var/spool/squid (CLEAN) 2009/01/16 09:30:24| Using Least Load store dir selection 2009/01/16 09:30:24| Set Current Directory to /var/spool/squid 2009/01/16 09:30:24| Loaded Icons. 2009/01/16 09:30:26| Accepting proxy HTTP connections at 0.0.0.0, port 8080, FD 11. 2009/01/16 09:30:26| Accepting ICP messages at 0.0.0.0, port 3130, FD 12. 2009/01/16 09:30:26| WCCP Disabled. 2009/01/16 09:30:26| Ready to serve requests. 2009/01/16 09:30:35| Store rebuilding is 0.4% complete 2009/01/16 09:30:53| Store rebuilding is 1.1% complete 2009/01/16 09:31:08| Store rebuilding is 1.5% complete 2009/01/16 09:31:24| Store rebuilding is 2.3% complete 2009/01/16 09:31:44| Store rebuilding is 3.1% complete 2009/01/16 09:32:01| Store rebuilding is 3.4% complete ... 2009/01/16 10:32:41| Store rebuilding is 98.1% complete 2009/01/16 10:33:06| Store rebuilding is 98.5% complete 2009/01/16 10:33:26| Store rebuilding is 98.9% complete 2009/01/16 10:33:53| Store rebuilding is 99.6% complete 2009/01/16 10:34:13| Done reading /var/spool/squid swaplog (1072895 entries) 2009/01/16 10:34:13| Finished rebuilding storage from disk. 2009/01/16 10:34:13| 1072895 Entries scanned 2009/01/16 10:34:13| 0 Invalid entries. 2009/01/16 10:34:13| 0 With invalid flags. 2009/01/16 10:34:13| 1044791 Objects loaded. 2009/01/16 10:34:13| 0 Objects expired. 2009/01/16 10:34:13| 0 Objects cancelled. 2009/01/16 10:34:13| 7253 Duplicate URLs purged. 2009/01/16 10:34:13| 20851 Swapfile clashes avoided. 2009/01/16 10:34:13| Took 3829.6 seconds ( 272.8 objects/sec). 2009/01/16 10:34:13| Beginning Validation Procedure 2009/01/16 10:35:04| 262144 Entries Validated so far. 2009/01/16 10:35:17| 524288 Entries Validated so far. 2009/01/16 10:35:25| 786432 Entries Validated so far. 2009/01/16 10:35:43| Completed Validation Procedure 2009/01/16 10:35:43| Validated 1044747 Entries 2009/01/16 10:35:43| store_swap_size = 15131260k 2009/01/16 10:37:58| storeLateRelease: released 4184 objects I never stop squid abnormally and I never restart server abnormally. So I don't understand why does squid do it. It takes a lot of CPU resources and about an hour of time. It never happened before. But now it happens several times a day. Could somebody help whith that? P.S. I have 18G partition with 16G granted for squid cache and 2G free for temporary squid files. So I hope it's enough space for squid to perform it's everyday tasks.
