Hi

I have a problem with my squid server.
I'm running the following configuration:

Browser - 80 - Squid - 3330 - InterscanVirusWall - 8080 - SquidOut -8080 - Internet

Squid and ISVirusWall are in the same PC (P4 2.0 GHz HD40GB 512MB RAM)

When the memory avaible in that machine is around 3 or 4 MByte, my users are unable to open https connections and all the browsing of protected pages is unavaible

this is my acl on the first squid server:

acl internet proxy_auth "/etc/squid/Internet"
acl password proxy_auth REQUIRED

acl all src 0.0.0.0/0.0.0.0
acl localhost src 127.0.0.1/32
acl vesta src 192.168.0.0/16

acl manager proto cache_object
acl SSL_ports port 443 563 441 440
acl Safe_ports port 21
acl Safe_ports port 443 563 441 440
acl Safe_ports port 70
acl Safe_ports port 210
acl Safe_ports port 1025-65535
acl Safe_ports port 280
acl Safe_ports port 488
acl Safe_ports port 591
acl Safe_ports port 777
acl Interscan port 3333
acl CONNECT method CONNECT

http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow CONNECT SSL_ports
http_access allow vesta internet
http_access deny all


have I to change my acl's or have I to setup my cahce_mem?Or is Interscan the problem?
