Well, I've just had another issue with my CPU usage gone bonkers. Here's the strace (compressed with gz): https://drive.google.com/file/d/0B-tpkY1LkI67WFBaNnVpR2lteEE/view?usp=sharing There are a lot of "Resource temporarily unavailable" messages. However, I'm seeing these messages even when my Squid process has been restarted, and everything seems to be OK from a "user experience" point of view. Do you see anything useful in the trace? If not, how can I improve the trace next time I have this issue? Here's what squidclient has to say during the "storm": HTTP/1.1 200 OK Server: squid Mime-Version: 1.0 Date: Thu, 26 Oct 2017 08:34:43 GMT Content-Type: text/plain;charset=utf-8 Expires: Thu, 26 Oct

37752578048 I read Alex's e-mail too late, so I'll try to attach gdb next time. The problem is that Squid continues to respond, but slowly. Having a backup Squid is not that simple in my scenario because I require to do content analysis on ssl-bumped traffic. I'm using TPROXY on the gateway/firewall with Squid. A true backup on this production system would mean having a full conntrackd'ed firewall with Squid as I cannot TPROXY on a redirected machine. I know Squid 4 is recommended for SSL-Bump, but it's still beta, and I'm not sure I can take that leap now. I didn't run mgr:events while the CPU was at 100%, but here's what came up afterwards: # squidclient mgr:events HTTP/1.1 200 OK Server: squid Mime-Version: 1.0 Date: Thu, 26 Oct 2017 11:02:42 GMT Content-Type: text/plain;charset=utf-8 Expires: Thu, 26 Oct 2017 11:02:42 GMT Last-Modified: Thu, 26 Oct 2017 11:02:42 GMT X-Cache: MISS from inf-fw2 X-Cache-Lookup: MISS from inf-fw2:3128 Connection: close Last event to run: MaintainSwapSpace Operation Next Execution Weight Callback Valid? logfileFlush 0.511 sec 1 yes MaintainSwapSpace 0.511 sec 1 N/A fqdncache_purgelru 1.481 sec 1 N/A idnsCheckQueue 2.507 sec 1 N/A statAvgTick 3.821 sec 1 N/A storeDirClean 5.484 sec 1 N/A memPoolCleanIdlePools 5.484 sec 1 N/A ipcache_purgelru 6.900 sec 1 N/A peerRefreshDNS 348.872 sec 1 N/A netdbSaveState 678.327 sec 1 N/A Adaptation::Icap::ServiceRep::noteTimeToUpdate 3243.778 sec 0 yes User Cache Maintenance 3302.980 sec 1 N/A storeDigestRebuildStart 3303.451 sec 1 N/A storeDigestRewriteStart 3303.451 sec 1 N/A # squidclient mgr:events HTTP/1.1 200 OK Server: squid Mime-Version: 1.0 Date: Thu, 26 Oct 2017 11:08:04 GMT Content-Type: text/plain;charset=utf-8 Expires: Thu, 26 Oct 2017 11:08:04 GMT Last-Modified: Thu, 26 Oct 2017 11:08:04 GMT X-Cache: MISS from inf-fw2 X-Cache-Lookup: MISS from inf-fw2:3128 Connection: close Last event to run: fqdncache_purgelru Operation Next Execution Weight Callback Valid? logfileFlush 0.141 sec 1 yes MaintainSwapSpace 0.141 sec 1 N/A idnsCheckQueue 3.212 sec 1 N/A ipcache_purgelru 5.393 sec 1 N/A fqdncache_purgelru 9.962 sec 1 N/A storeDirClean 13.942 sec 1 N/A memPoolCleanIdlePools 13.942 sec 1 N/A peerRefreshDNS 27.243 sec 1 N/A statAvgTick 42.223 sec 1 N/A netdbSaveState 356.698 sec 1 N/A Adaptation::Icap::ServiceRep::noteTimeToUpdate 2922.149 sec 0 yes User Cache Maintenance 2981.351 sec 1 N/A storeDigestRebuildStart 2981.822 sec 1 N/A storeDigestRewriteStart 2981.822 sec 1 N/A I haven't been able to associate the 100% CPU issue with a scheduled event.
