Sorry to bring this back up, but every now and then (few days) I need to restart squid because its CPU usage goes up to 100% for a long time (irresponsive). Right before restarting Squid: # free [11/07/17 11:18:52] total used free shared buff/cache available Mem: 32865056 14811320 1374212 157028 16679524 17557656 Swap: 37036988 287320 36749668 # squidclient mgr:info [11/07/17 11:18:52] # squidclient mgr:mem [11/07/17 11:19:02] # squidclient mgr:storedir [11/07/17 11:19:22] # squidclient mgr:filedescriptors [11/07/17 11:19:42] # squidclient mgr:events [11/07/17 11:20:12] In other words, squidclient does not get any info from squid (waited max 30 seconds - maybe I need to wait more). I also dumped an strace here: https://drive.google.com/file/d/1yed-sNWrc6KBQSOV7KPbrYOForwwtkCe/view?usp=sharing You probably won't be able to draw any conclusions so I'll try to update to squid-3.5.27-20171101-re69e56c (I'm now running 3.5.27-20170916-re69e56c). Note that stopping Squid with: /usr/sbin/squid -k shutdown -f /etc/squid/squid.conf -n squid takes a LONG time, but it eventually does stop (the process dies out). I can then restart it cleanly. I don't need to kill the pid (unless I'm told to hurry up). After checking the log I can see these messages: 2017/11/07 11:16:59 kid1| WARNING!

Is this weird, or should I really increase this value?
