[squid-users] Squid and NTLM Error

Hi

i have a lot of error into my cache.log of squid:

2009/03/16 07:44:47| WARNING: up to 149 pending requests queued

I think's it's this config:

auth_param ntlm program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 35
#auth_param ntlm use_ntlm_negotiate on
#auth_param ntlm max_challenge_reuses 0
#auth_param ntlm max_challenge_lifetime 10 minutes

auth_param basic program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-basic
auth_param basic children 15
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours

Correct ?
What is the best configuration for NTLM ?

Thanks
