[squid-users] CLOSE_WAIT

I have a busy Squid 3.2.3 server that constantly has a huge number of
connections tied up in CLOSE_WAIT (i.e. at the moment it has 364

tcp 1 0 ::ffff:
::ffff: CLOSE_WAIT 32303/(squid-1)

All of these sockets have an rx queue containing 1 byte. I'm aware that
I can reduce client_lifetime, but I'm wondering if I have a more
fundamental problem somewhere since Squid appears to not be flushing the
queue. Can anyone cast any light onto this behaviour?

Other servers running various versions of Squid (including 3.2.3) don't
seem to be exhibiting the problem to such an extent (I'm still seeing a
number of CLOSE_WAIT sockets with an rx queue length of 1 on these
servers, but in relatively small quantities.)
