There is no "Open Filedescriptors" in my cachemgr, but I see Process
Filedescriptor Allocation
3 Log 0 0 0 /var/log/squid/cache71.log
7 File 0 0 2943 /var/log/squid/access71.log
3 Socket 0 1520 494 .0 DNS Socket
4 Socket 0 0* 0 .0 HTTP Socket
15 Socket 1440 63* 0 x.x.x.x.xxxx
cache_object://ra/filedescriptors

After squid starts, I see "OPEN CONNS : 0" in "Peer Cache Statistics"
After I download something, I sees "OPEN CONNS : 3" , but
netstat shows, that there is no connections to the parent!
(I think, it is not netstat's "Active UNIX domain sockets".
I checked only "Active Internet connections")

I checked - "OPENS CONNS" didn't decrease after 10 minutes.
It becomes 0 only after "squid -k reconfigure".

So, max-conn counter counts wrong?!
