Hello, Squid3 seems to keep a LOT (over a thousand) idle connections to its parent proxy. To me it seems as if doesn't properly reuse existing connections. Is there a way to find out what's going on? From what I can see there are not more than about two dozens requests at the same time. I already reduced pconn_timeout to 10 seconds to reduce the number of connections that are open to around 100. Kind regards Malte
