Hi, After a long time working correctly, Squid stops working all of a sudden. No new requests/replies show up in the logs. Complete silence. If I issue "squid -k reconfigure" I get this message in cache.log: Set Current Directory to /var/cache/squid If I set "debug_options rotate=1 ALL,9" and run "squid -k reconfigure" twice then I get this in cache.log: 2017/08/23 07:54:32.676| 21,3| tools.cc(610) enter_suid: enter_suid: PID 17797 taking root privileges 2017/08/23 07:54:32.676| 13,3| mem.cc(473) Report: Memory pools are 'on'; limit: 5.000 MB 2017/08/23 07:54:32.676| Set Current Directory to /var/cache/squid 2017/08/23 07:54:32.676| 21,3| tools.cc(543) leave_suid: leave_suid: PID 17797 called 2017/08/23 07:54:32.676| 21,3| tools.cc(565) leave_suid: leave_suid: PID 17797 giving up root, becoming 'squid' 2017/08/23 07:55:01.605| 21,3| tools.cc(610) enter_suid: enter_suid: PID 17927 taking root privileges 2017/08/23 07:55:01.605| 13,3| mem.cc(473) Report: Memory pools are 'on'; limit: 5.000 MB 2017/08/23 07:55:01.605| Set Current Directory to /var/cache/squid 2017/08/23 07:55:01.605| 21,3| tools.cc(543) leave_suid: leave_suid: PID 17927 called 2017/08/23 07:55:01.605| 21,3| tools.cc(565) leave_suid: leave_suid: PID 17927 giving up root, becoming 'squid' However, any attempt to browse the web leads to nothing new in the logs. Finally, stopping the squid service fails. I can list the squid processes: # ps -ae | grep squid 4439 ? 05:29:57 squid 9059 ? 00:00:00 squid 9160 ? 00:00:00 squid 9162 ? 00:11:42 squid 9206 ? 00:00:00 squid 9208 ? 00:02:04 squid 9254 ? 00:00:00 squid 9257 ? 00:00:28 squid 9313 ? 00:00:00 squid 9315 ? 00:00:55 squid I have to kill these processes in order to start squid again. # squid -version Squid Cache: Version 3.5.26 Service Name: squid This binary uses OpenSSL 1.0.2k 26 Jan 2017.
