Hi I'm using 3.2.5 with four workers (workers 4). Each worker has its own cache_dir: workers 4 cache_dir aufs /squid-cache0${process_number} 100000 64 512 cache_dir aufs /squid-cache0${process_number} 100000 64 512 cache_dir aufs /squid-cache0${process_number} 100000 64 512 cache_dir aufs /squid-cache0${process_number} 100000 64 512 When I now reconfigure squid with "squid -f /etc/squid/squid.conf -k reconfigure" or "squidclient mgr:reconfigure", then I got the following error in the cache.log: 2013/01/07 14:34:54 kid5| /squid-cache05/swap.state: (2) No such file or directory After this reconfigure, squidclient is no more usable (it always throws an 404). After this reconfigure, the main process for the 3128er-listener is then not the process "squid-coord-5" ->it's one of the kid-process. $ netstat -pantue | grep 3128 tcp 0 0 0.0.0.0:3128 0.0.0.0:* LISTEN 0 1441481 20003/(squid-coord-5) $ squidclient mgr:reconfigure $ netstat -pantue | grep 3128 tcp 0 0 0.0.0.0:3128 0.0.0.0:* LISTEN 0 1448779 20004/(squid-4) $ squidclient mgr:info HTTP/1.1 404 Not Found Server: squid Mime-Version: 1.0 Date: Mon, 07 Jan 2013 13:58:37 GMT Content-Type: text/html Content-Length: 3299 X-Squid-Error: ERR_INVALID_URL 0 Vary: Accept-Language Content-Language: en ... ... Why does squid spawns a kid5-process (after the reconfigure) with a fifth cache_dir although there are just four configured? How can I reconfigure squid properly with workers running? Many thanks. Kind regards, Tom
