[squid-users] Connection error

Hi All,

I am using Squid Cache: Version 3.1.8, configured NTLM scheme using
samba, CLAM Av + ICAP and Squid guard.
All of the clients are Windows machine joined in domain. The browser
authenticates using ntlm scheme without pop up for password and
everything working fine.

We have two issues:
1.We are using many acls to allow and deny websites on the basis of the
ADS groups using wbinfo.pl. Time to time the users are reporting that
the authentication pop up occurs .
In cache.log we can find the following

2011/01/14 12:27:50| WARNING: All ntlmauthenticator processes are busy.
2011/01/14 12:27:50| WARNING: 25 pending requests queued

We just increased it to 30 for ntlm and 30 for wbinfo(external) still it
occurs. Does ntlm scheme has any new behaviour?

2.When we browse a website and leave browser idle for 30 - 60 minutes ,
cannot display page occurs.
In squid.conf we have used following values
half_closed_clients off
client_persistent_connections off
server_persistent_connections off
Whether squid has this as default behaviour?, suggest s suitable options
in squid conf to overcome it.

Thanks
Senthil
