Hello. I wrote earlier in wrong location: http://bugs.squid-cache.org/show_bug.cgi?id=4647 > Squid eats all RAM, then eats all swap in a hour and killed by kernel. >I was try to turn off cache, change squid version, change some configuration parameters by this guide http://wiki.squid-cache.org/SquidFaq/SquidMemory except malloc, but nothing helps. I made some config changes in accordance with the advice of Amos Jeffries (via on). But it does not help. This trouble somehow linked with https. If wccp redirects only 80 port - works fine. wccp2_service_info 70 protocol = tcp flags = dst_ip_hash priority = 231 ports = 80 If wccp redirects 443 too - then squid overflows and killed by kernel wccp2_service_info 70 protocol = tcp flags = dst_ip_hash priority = 231 ports = 80,443 ---Before it died (HTTPS on): Mem: 16291720k total, 16125288k used, 166432k free, 540k buffers Swap: 8216568k total, 8112628k used, 103940k free, 27112k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30858 squid 20 0 22.7g 14g 3612 S 8.0 94.6 14:50.82 squid # free -m total used free shared buffers cached Mem: 15909 15750 158 0 0 26 -/+ buffers/cache: 15723 186 Swap: 8023 7936 87 Start Time: Sat, 10 Dec 2016 07:52:50 GMT Current Time: Sat, 10 Dec 2016 09:39:45 GMT Connection information for squid: Number of clients accessing cache: 1305 Number of HTTP requests received: 193434 Number of ICP messages received: 0 Number of ICP messages sent: 0 Number of queued ICP replies: 0 Number of HTCP messages received: 0 Number of HTCP messages sent: 0 Request failure ratio: 0.00 Average HTTP requests per minute since start: 1809.2 Average ICP messages per minute since start: 0.0 Select loop called: 4529796 times, 1.416 ms avg Cache information for squid: Hits as % of all requests: 5min: 0.0%, 60min: 0.0% Hits as % of bytes sent: 5min: 0.1%, 60min: -0.0% Memory hits as % of hit requests: 5min: 0.0%, 60min: 0.0% Disk hits as % of hit requests: 5min: 0.0%, 60min: 0.0% Storage Swap size: 82044 KB Storage Swap capacity: 80.1% used, 19.9% free Storage Mem size: 107876 KB Storage Mem capacity: 20.6% used, 79.4% free Mean Object Size: 29.54 KB Requests given to unlinkd: 9258 Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.10857 0.04519 Cache Misses: 0.01648 0.00678 Cache Hits: 0.00000 0.00000 Near Hits: 0.00000 0.00000 Not-Modified Replies: 0.00000 0.00000 DNS Lookups: 0.00860 0.00779 ICP Queries: 0.00000 0.00000 Resource usage for squid: UP Time: 6415.101 seconds CPU Time: 902.767 seconds CPU Usage: 14.07% CPU Usage, 5 minute avg: 15.97% CPU Usage, 60 minute avg: 13.96% Maximum Resident Size: 62241760 KB Page faults with physical i/o: 32647 Memory accounted for: Total accounted: 1073388 KB memPoolAlloc calls: 12969 memPoolFree calls: 35802441 File descriptor usage for squid: Maximum number of file descriptors: 100000 Largest file desc currently in use: 28744 Number of file desc currently in use: 28738 Files queued for open: 0 Available number of file descriptors: 71262 Reserved number of file descriptors: 100 Store Disk files open: 0 Internal Data Structures: 57337 StoreEntries 54560 StoreEntries with MemObjects 52 Hot Object Cache Items 2777 on-disk objects ---after: /var/log/messages kernel: 11733 total pagecache pages kernel: 8957 pages in swap cache kernel: Swap cache stats: add 21118384, delete 21109427, find 12110273/12422740 kernel: Free swap = 0kB kernel: Total swap = 8216568kB kernel: 4194303 pages RAM kernel: 121373 pages reserved kernel: 11781 pages shared kernel: 4023631 pages non-shared ...omitted... kernel: Out of memory: Kill process 30858 (squid) score 954 or sacrifice child kernel: Killed process 30868, UID 23, (log_file_daemon) total-vm:26640kB, anon-rss:48kB, file-rss:512kB (squid-1): I don't handle this error well!
